Wang, Qiang;Yan, Zilong;Xing, Dong research published 《 Nickel(0)-catalyzed linear-selective hydroarylation of 2-aminostyrenes with arylboronic acids by a bifunctional temporary directing group strategy》, the research content is summarized as follows. A nickel(0)-catalyzed linear-selective hydroarylation of 2-aminostyrenes with arylboronic acids using a bifunctional temporary directing group strategy was reported. In the presence of a catalytic amount of com. available 3,5-dibromosalicylaldehyde, an aldimine intermediate is formed to interact with the nickel(0) catalyst by both chelation from the imino group and nickel-hydride formation from the phenoxy group. With the imino-assisted six-membered metallacycle formation, excellent linear selectivity has been achieved for this redox-neutral hydroarylation reaction.

Sundaresan, Sriram;Kuhne, Irina A.;Evesson, Colin;Harris, Michelle M.;Fitzpatrick, Anthony J.;Ahmed, Ahmed;Muller-Bunz, Helge;Morgan, Grace G. research published 《 Compressed Jahn-Teller octahedra and spin quintet-triplet switching in coordinatively elastic manganese(III) complexes》, the research content is summarized as follows. Complex assembly preferences and resultant spin state choice and Jahn-Teller distortion mode in twelve Mn(III) complexes of varying nuclearity with Schiff base chelate ligands of different sizes are compared. Mononuclear complexes [Mn(5-F-Sal₂323)]OTf (1), [Mn(5-F-Sal₂323)]ClO₄ (2) and [Mn(5-F-Sal₂323)]NO₃, (3) with the 8-carbon R-Sal₂323 chelate type show rare axial compression at room temperature and complexes (2) and (3) also show reversible thermal spin state switching from spin quintet to triplet states on cooling. The prevalence of atypical axial compression is further probed by single crystal diffraction studies on high spin mononuclear complexes (4)-(7) with the longer 9-carbon R-Sal₂333 chelate series using [Mn(3-OEt-Sal₂333)]BF₄, (4) [Mn(3,5-diOMe-Sal₂333)]BF₄·0.5PrOH, (5), [Mn(5-F-Sal₂333)]BPh₄, (6) and [Mn(5-NO₂-Sal₂333)]BPh₄, (7) as examples. Ring closure of both the 8-carbon R-Sal₂323 and longer 9-carbon R-Sal₂333 ligands was also observed yielding a ligand with a 6-membered ring in the mononuclear complex [Mn(3-OMe,5-NO₂-Sal₂333^6R)]·0.07MeOH·0.93MeCN (8) in contrast to a protonated 5-membered ring in the dimeric complex [Mn₂(5-Cl-Sal₂323^H5R)₂](ClO₄)₂·1.85EtOH·0.33MeCN, (9) with the R-Sal₂323 chelate type. Finally comparison of the assembly modes of Mn(III) complexes of the 8-carbon R-Sal₂323 and 9-carbon R-Sal₂333 series with those of the shorter 7-carbon R-Sal₂322 ligand series reveal that the mononuclear assembly mode is not favored with the smaller chelate. Instead three dimeric or cluster complexes with rearranged ligands were recovered in low yield. The structures of these complexes [Mn₂(5-NO₂-Sal₂322^5R)₂]·2BuOH, (10), [Mn₂(3,5-diBr-Sal₂322^5R)(3,5-diBr-Sal)₃]·0.7EtOH·2.61MeCN, (11) and [Mn₂Na(3-NO₂,5-OMe-Sal₂322^5R)]ClO₄·0.5MeCN (12) are reported and compared with examples with the longer chain R-Sal₂323 and R-Sal₂333 chelate ligands.

Siloxane-based elastomers are some of the most sought-after materials for the construction of actuators and equipment for energy harvesting devices. This article focuses on changes of the mech. (breaking stress, breaking strain, Young′s modulus) and dielec. properties for elastomers prepared with silicones, induced by the variation of mol. weight of the matrix, with three different silicone polymers having 60,000 g/mol, 150,000 g/mol, and 450,000 g/mol (from GPC measurements). Multiple siloxane elastomers were crosslinked with methyltriacetoxysilane using the sol-gel route. The dielec. permittivity values of the elastomers were also enhanced with two different complex structures containing siloxane bond and 3d transition metals as filler materials for polydimethylsiloxane polymers with various mol. weights The dielec. spectroscopy tests demonstrated a small decrease (5%) for the values of the dielec. permittivity in relation to increased mol. weight of the siloxane polymer, both for samples prepared with pure polymer and for samples with metal complexes. The samples of nanocomposites showed a >50% increase of dielec. permittivity values relative to samples prepared of pure siloxane elastomer. The thermal tests demonstrated that the nanocomposites retained thermal stability similar with samples prepared of pure siloxane elastomer. The behavior under controlled conditions of humidity showed a trend of increased water vapor sorption with increasing mol. weight but an overall hydrophobic stable character of nanocomposites.

Shool, Maryam Taghizadeh;Rudbari, Hadi Amiri;Gil-Anton, Tania;Cuevas-Vicario, Jose V.;Garcia, Begona;Busto, Natalia;Moini, Nakisa;Blacque, Olivier research published 《 The effect of halogenation of salicylaldehyde on the antiproliferative activities of {Δ/Λ-[Ru(bpy)₂(X,Y-sal)]BF₄} complexes》, the research content is summarized as follows. Ru(II) polypyridyl complexes are widely used in biol. fields, due to their physicochem. and photophys. properties. New chiral Ru(II) polypyridyl complexes (1–5) {Δ/Λ-[Ru(bpy)₂(X,Y-sal)]BF₄} (bpy = 2,2′-bipyridyl; X,Y-sal = 5-bromosalicylaldehyde 1, 3,5-dibromosalicylaldehyde 2, 5-chlorosalicylaldehyde 3, 3,5-dichlorosalicylaldehyde 4 and 3-bromo-5-chlorosalicylaldehyde 5) were synthesized and characterized by elemental anal., FTIR, and ¹H/¹³C NMR spectroscopy. The structures of 1 and 5 were determined by x-ray crystallog. and showed that the central Ru adopts a distorted octahedral coordination sphere with two bpy and one halogen-substituted salicylaldehyde. DFT and TD-DFT calculations were performed to explain the excited states of these complexes. The singlet states with higher oscillator strength are correlated with the absorption signals and are mainly described as ¹MLCT from the Ru center to the bpy ligands. The lowest triplet states (T₁) are described as ³MLCT from the Ru center to the salicylaldehyde ligand. The theor. results are in good agreement with the observed unstructured band at ∼520 nm for complexes 2, 4 and 5. Biol. studies on human cancer cells revealed that dihalogenated ligands endow the Ru(II) complexes with enhanced cytotoxicity compared to monohalogenated ligands. As far as the type of halogen is concerned, Br is the halogen that provides the highest cytotoxicity to the synthesized complexes. All complexes induce cell cycle arrest in G0/G1 and apoptosis, but only complexes bearing Br are able to provoke an increase in intracellular ROS levels and mitochondrial dysfunction.

The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
