Employing anilines as nucleophiles in double carbonylation is a longstanding challenge. In this communication, a Mn(III)-promoted double carbonylation of alkylborates or Hantzsch esters with anilines toward the synthesis of α-ketoamides has been developed. By using easily available potassium alkyltrifluoroborates or Hantzsch esters as the starting material, and cheap and non-toxic Mn(OAc)₃ · 2H₂O as the promotor, a broad range of alkyl α-ketoamide derivatives were synthesized in moderate to good yields with excellent selectivity.

Wojcieszak, Marta published the artcileSurface activity and phytotoxicity of morpholinium herbicidal ionic liquids, HPLC of Formula: 111-83-1, the publication is Journal of Molecular Liquids (2022), 119750, database is CAplus.

The use of efficient synthesis methods to obtain novel herbicidal ionic liquids (HILs) with biol. activity is extremely important because it can eliminate certain neg. environmental impacts. The authors of this work succeeded in the experiment, which resulted in the synthesis of 18 novel ionic liquids with high yields. Furthermore, a number of physicochem. and biol. properties have been investigated, including surface activity, thermal anal., and phytotoxicity. In addition, it was proven that morpholinium ionic liquids with phenoxyacid anions were more effective against cress than HILs previously studied in the literature. To the best of our knowledge, this is the first report of surface-active ionic liquids with herbicidal anions where leaf surfaces were used for anal. An important aspect of this work was to compare the wettability of the surfaces of wheat leaves and weeds. Moreover, it was shown that using paraffin as a reference surface was not sufficient to describe the wetting properties of HILs. The research reported here proved that morpholinium ionic liquids were effective in wetting weed surfaces while they do not adversely affect wheat leaf surfaces. Our results could be significant for meeting the environmental challenges and agricultural demands of the future.

Derince, Betul published the artcileArchitectural design of new conjugated systems carrying donor-π-acceptor groups (carbazole-CF₃): Characterizations, optical, photophysical properties and DSSC′s applications, SDS of cas: 111-83-1, the publication is Journal of Molecular Structure (2022), 1250(Part_2), 131689, database is CAplus.

In this study, two new organic dyes containing substituted N-octyl carbazole as electron donor and -CF₃ units as electron acceptor group were designed and synthesized for ZnO-based dye sensitized solar cells (DSSCs). The synthesized carbazole derivatized compounds 3,6-bis(3,5-bis(trifluoromethyl)phenyl)-9-octyl-9H-carbazole (IVa) and 3,6-bis(4-(trifluoromethyl)phenyl)-9-octyl-9H-carbazole (IVb) were characterized by FT-IR, ¹H NMR, ¹³C NMR, HMBC and CHN analyses. The spectroscopic (UV-Vis and FL) and thermal properties (TGA-DTA) of these compounds were also investigated. The produced (IVa and IVb) ZnO films were used as photoanodes in all DSSCs. Microwave-assisted hydrothermal method was used to synthesize ZnO nanopowders with different morphologies which are used as photoanodes in DSSCs. The structural and morphol. properties of ZnO nanopowders were investigated using X-ray diffraction (XRD) and field emission SEM (FESEM). ZnO-DSSCs were produced through coating ZnO nanopowders on transparent conductive fluorine-doped tin oxide (FTO) coated glass substrate using the Doctor Blade method. Current-voltage measurements of all produced DSSCs were carried out under a solar simulator with AM 1.5 G filter having an irradiance of 100 mW/cm². Solar cell performances of all DSSCs such as; open-circuit voltage (V_oc), short circuit current (J_sc), fill factor (FF) and power conversion efficiency (PCE) were analyzed.

Blake, Matthew R. published the artcileSmall Molecules Targeting PTPσ-Trk Interactions Promote Sympathetic Nerve Regeneration, Category: bromides-buliding-blocks, the publication is ACS Chemical Neuroscience (2022), 13(5), 688-699, database is CAplus and MEDLINE.

Chondroitin sulfate proteoglycans (CSPGs) prevent sympathetic nerve regeneration in the heart after myocardial infarction and prevent central nerve regrowth after traumatic brain injury and spinal cord injury. Currently, there are no small-mol. therapeutics to promote nerve regeneration through CSPG-containing scars. CSPGs bind to monomers of receptor protein tyrosine phosphatase sigma (PTPσ) on the surface of neurons, enhancing the ability of PTPσ to bind and dephosphorylate tropomyosin receptor kinases (Trks), inhibiting their activity and preventing axon outgrowth. Targeting PTPσ-Trk interactions is thus a potential therapeutic target. Here, we describe the development and synthesis of small mols. (HJ-01 and HJ-02) that disrupt PTPσ interactions with Trks, enhance Trk signaling, and promote sympathetic nerve regeneration over CSPGs.

Authors report the use of imidazolium based tunable aryl alkyl ionic liquids (TAAILs) as solvents in the Mizoroki-Heck reaction. Different com. available palladium sources, inorganic bases, TAAILs and reaction conditions were tested for the synthesis of trans-stilbene using bromobenzene and styrene. A variety of different stilbene derivatives were synthesized with exclusive formation of the (E)-isomers and isolated yields up to 97%. Author’s were able to optimize the reaction conditions using only 0.25 mol% of Pd(OAc)₂ as the catalyst and a reaction time of 4 h. No addnl. ligands or additives are used in the reaction. The catalytic system using TAAILs achieved higher yields than com. available imidazolium and phosphonium ionic liquids, demonstrating the potential of tailored ionic liquids as a reaction medium for the Mizoroki-Heck reaction.

El-Saeed, H. M. published the artcileSynthesis and characterization of novel ionic liquids based on imidazolium for acid corrosion inhibition of aluminum: Experimental, spectral, and computational study, Recommanded Product: 1-Bromooctane, the publication is Journal of Molecular Liquids (2022), 119177, database is CAplus.

Three newly ionic liquids I [R = C₈H₁₇, C₁₀H₂₁, C₁₂H₂₅] were synthesized and their chem. structures characterized via different spectra techniques (FT-IR, elemental anal., and ¹H NMR). The corrosion inhibition of newly ionic liquids was evaluated on aluminum alloy in 1 M HCl at varied exposure temperatures (298-318 K) and varied concentrations via various exptl. and theor. methods for example mass loss, electrochem., spectral, and computational calculations The results illustrate that these types of ionic liquids inhibit corrosion of aluminum in acid solution with maximum inhibition efficiency was reached 83.2% at 298 K. The inhibition efficiency increases with the addition of zinc sulfate which had a synergistic impact which was reached to 92.7%. Also, the concentration of ionic liquids and the kind of cation have an impact on the obtained results. The existence of these inhibitors in the acidic solution improves the charge transfer resistance and lessens the double-layer capacitance. The Langmuir adsorption isotherm governs the adsorption of these inhibitors’ mols. on the aluminum alloy surface, and they behave as mixed-type inhibitors. The outputs reveal that the computational calculations match the exptl. data rather well.

Chen, Shipeng published the artcileThe remarkable role of hydrogen bond, halogen, and solvent effect on self-healing supramolecular gel, Recommanded Product: 1-Bromooctane, the publication is Materials Today Chemistry (2022), 100719, database is CAplus.

Self-healing supramol. gels of low-mol.-weight (LMW) mols. are smart soft materials; however, the development of self-healing LMW gelator is still a challenging task because of the lack of in-depth studies about self-healing mechanisms of LMW gels and the solvent effect on gel properties. Therefore, herein a different perspective was used to study a family of D-gluconic acetal-based gelators with variable structural fragments in 14 different solvents, and a more detailed understanding of self-assembly and self-healing mechanism of supramol. gels was attained. Based on the critical gelation concentration, phase transition temperature, and rheol. data, A8 bearing an amide group in side chain and two chlorine atoms linked to benzene ring was found to be an outstanding gelator, which could form gels with good self-healing ability in a variety of solvents. Interestingly, A8 gel formed in n-BuOH demonstrates high transparency, good mech. strength, self-supporting behavior, and great self-healing ability from mech. damage. Based on the Fourier transform IR spectroscopy, NMR spectroscopy, XPS, X-ray diffraction, and theor. calculation anal., the self-assembly and self-healing mechanisms of A8 gel were proposed, indicating that a combination of hydrogen bonding and halogen effect was responsible for the efficient self-healing behavior of supramol. gel. Furthermore, the anal. of solvent parameters indicated that the dispersion force of solvent favored gelators to self-assemble, hydrogen bonding donor ability of solvent mainly affected the formation of one-dimensional assembly, and hydrogen bonding receptor ability and polarity of solvent mainly influenced the supramol. interactions among assemblies, significantly intervening the self-healing ability of gels. Overall, this study provides a new perspective to the understanding of gelator structure-property correlation in solvents and sheds light for future development of self-healing supramol. gels.

Nhari, Laila M. published the artcilePhenothiazine-based dyes containing imidazole with π-linkers of benzene, furan and thiophene: Synthesis, photophysical, electrochemical and computational investigation, Quality Control of 111-83-1, the publication is Journal of Molecular Structure (2022), 131959, database is CAplus.

Three newly designed phenothiazine-based dyes were synthesized in good yield by introducing 1,4,5-tri-Ph imidazole to phenothiazine skeleton linked to benzene, furan or thiophene π-linkers and connected with cyanoacrylic acid acceptor as the anchoring, resp. UV-vis absorption and fluorescence properties of phenothiazine-based dyes were studied in different solvents. Among π-linkers, furan revealed the highest red shift of absorption, followed by thiophene and benzene. The dyes show intense visible absorption with high molar absorptivity; hence good light-harvesting dyes when used as sensitizers. The cyclic voltammetry data revealed that the HOMO energy levels of phenothiazine-based dyes were 5.36 eV for dye I and 5.42 eV for dyes II and III. Also, the energy LUMO levels of phenothiazine-based dyes were -3.10, -3.21, and -3.26 eV for phenothiazine-based dyes, resp. Such well-matched energy levels of these dyes with those reported sensitizers would pave the way for their use in photovoltaic devices. Furthermore, these dyes were investigated by D. Functional Theory (DFT) and time-dependent TD-DFT to explore their potential as efficient dyes in photovoltaic devices. The geometrical structures, optoelectronic properties and charge transfer of these dyes were investigated. The results indicate that the phenothiazine-based dyes have a small energy gap, absorption in the visible and higher oscillator strength. The modification of Ph, furan and thiophene suggests that these dyes could be effective for dye-sensitized solar cells (DSSCs).

Khudozhitkov, Alexander E. published the artcileHigh-Temperature Quantum Tunneling and Hydrogen Bonding Rearrangements Characterize the Solid-Solid Phase Transitions in a Phosphonium-Based Protic Ionic Liquid, Name: 1-Bromooctane, the publication is Chemistry – A European Journal (2022), 28(23), e202200257, database is CAplus and MEDLINE.

Authors report the complex phase behavior of the glass forming protic ionic liquid (PIL) d3-octylphosphonium bis(trifluoromethylsulfonyl)imide [C₈H₁₇PD₃][NTf₂] by solid-state NMR spectroscopy. Combined line shape and spin relaxation studies of the deuterons in the PD₃ group of the octylphosphonium cation allow to map and correlate the phase behavior for a broad temperature range from 71 K to 343 K. In the solid PIL at 71 K, we observed a static state, characterized by the first deuteron quadrupole coupling constant reported for PD₃ deuterons. A transition enthalpy of about 12 kJ mol^-1 from the static to the mobile state with increasing temperature suggests the breaking of a weak, charge-enhanced hydrogen bond between cation and anion. The highly mobile phase above 100 K exhibits an almost disappearing activation barrier, strongly indicating quantum tunneling. Thus, they provide first evidence of tunneling driven mobility of the hydrogen bonded P-D moieties in the glassy state of PILs, already at surprisingly high temperatures up to 200 K. Above 250 K, the mobile phase turns from anisotropic to isotropic motion, and indicates strong internal rotation of the PD₃ group. The analyzed line shapes and spin relaxation times allow us to link the structural and dynamical behavior at mol. level with the phase behavior beyond the DSC traces.
