Akther, Thamina published the artcileSynthesis and Structures of [2.n]Metacyclophan-1-enes and their Conversion to Highly Strained [2.n]Metacyclophane-1-ynes, COA of Formula: C10H16Br3N, the publication is European Journal of Organic Chemistry (2020), 2020(27), 4167-4175, database is CAplus.

The syntheses of syn-[2.n]metacyclophan-1-enes (n = 5, 6, 8) in good yields using the McMurry cyclization of 1,n-bis(3-formyl-4-methoxyphenyl)alkanes are reported. Conversion of syn-[2.6]- and [2.8]metacyclophan-1-enes to the corresponding highly strained syn-type [2.6]- and [2.8]metacyclophane-1-ynes was achieved by successive bromination and dehydrobromination reactions. An attempted trapping reaction of the putative corresponding [2.5]metacyclophane-1-yne by Diels-Alder reaction with 1,3-diphenylisobenzofuran failed due to its smaller ring size and strained structure. X-ray crystallog. analyses show that the triple bonds in syn-[2.6]- and [2.8]metacyclophane-1-ynes are distorted from linearity with bond angles of 156.7° and 161.4°, resp. A DFT (D. Functional Theory) computational study was conducted to determine the stabilities of different conformations of the target compounds

Ito, Akihiro published the artcileFacile Synthesis, Crystal Structures, and High-Spin Cationic States of All-para-Brominated Oligo(N-phenyl-m-aniline)s, Related Products of bromides-buliding-blocks, the publication is Journal of Organic Chemistry (2002), 67(2), 491-498, database is CAplus and MEDLINE.

Syntheses of brominated oligoanilines I and II were achieved in a one-pot procedure from the parent nonbrominated oligomers and benzyltrimethylammonium tribromide [(BTMA)Br₃]. An X-ray crystallog. anal. revealed that II has a U-shaped structure, suggesting that the analogous polymer easily adopts helical structures. Furthermore, the redox properties were investigated by the UV-vis and EPR measurements. It was confirmed that the both I and II can be oxidized into the dications I²⁺ and II²⁺ with triplet spin-multiplicity.

Matsunaga, Yoichiro published the artcileReactions of 3-isopropenyl- and 3-acetyltropolone with quaternary ammonium tribromides, Related Products of bromides-buliding-blocks, the publication is Bulletin of the Chemical Society of Japan (1992), 65(1), 295-7, database is CAplus.

Treatments of 3-isopropenyltropolone (I) with quaternary ammonium tribromides in THF afforded 3-methyl-8H-cyclohepta[b]furan-8-one (II). The reactions in methanol-dichloromethane gave 7-bromo-3-methyl-8H-cyclohepta[b]furan-8-one. Bromination of 3-acetyltropolone with the tribromides in THF produced 3-(bromoacetyl)tropolone, whereas the reaction in the methanolic solvent gave 7-bromo- and 5,7-dibromo-substituted 3-acetyltropolones. The brominations of 4′-hydroxyacetophenone were also carried out.

Williams, Sierra J. published the artcileOrthogonal bioluminescent probes from disubstituted luciferins, COA of Formula: C10H16Br3N, the publication is Biochemistry (2021), 60(8), 563-572, database is CAplus and MEDLINE.

Bioluminescence imaging with luciferase-luciferin pairs is routinely used to monitor cellular functions. Multiple targets can be visualized in tandem using luciferases that process unique substrates, but only a handful of such orthogonal probes are known. Multiplexed studies require addnl. robust, light-emitting mols. In this work, we report new luciferins for orthogonal imaging that comprise disubstituted cores. These probes were found to be bright emitters with various engineered luciferases. The unique patterns of light output also provided insight into enzyme-substrate interactions necessary for productive emission. Screening studies identified mutant luciferases that could preferentially process the disubstituted analogs, enabling orthogonal imaging with existing bioluminescent reporters. Further mutational analyses revealed the origins of substrate selectivity. Collectively, this work provides insights into luciferase-luciferin features relevant to bioluminescence and expands the number of probes for multicomponent tracking.

Feng, Xing published the artcilePyrene-Based Y-shaped Solid-State Blue Emitters: Synthesis, Characterization, and Photoluminescence, HPLC of Formula: 111865-47-5, the publication is Chemistry – An Asian Journal (2012), 7(12), 2854-2863, S2854/1-S2854/29, database is CAplus and MEDLINE.

A series of pyrene-based Y-shaped blue emitters, namely, 7-tert-butyl-1,3-diarylpyrenes 4 were synthesized by the Suzuki cross-coupling reaction of 7-tert-butyl-1,3-dibromopyrene with a variety of p-substituted phenylboronic acids in good to excellent yields. These compounds were fully characterized by X-ray crystallog., UV/Vis absorption and fluorescence spectroscopy, DFT calculations, thermogravimetric anal., and differential scanning calorimetry. Single-crystal X-ray anal. revealed that the Y-shaped arylpyrenes exhibited a low degree of π stacking owing to the steric effect of the bulky tert-Bu group in the pyrene ring at the 7-position, and thus, the intermol. π-π interactions were effectively suppressed in the solid state. Despite the significantly twisted nonplanar structures, these mols. still displayed efficient intramol. charge-transfer emissions with clear solvatochromic shifts on increasing solvent polarity. An intriguing fact is that all of these mols. show highly blue emissions with excellent quantum yields in the solid state. Addnl., the two compounds containing the strongest electron-accepting groups, CN (4 d) and CHO (4 f), possess high thermal stability, which, together with their excellent solid-state fluorescence efficiency, makes them promising potential blue emitters in organic light-emitting device applications.

Jordan, Alfonzo D. published the artcileEfficient Conversion of Substituted Aryl Thioureas to 2-Aminobenzothiazoles Using Benzyltrimethylammonium Tribromide, Safety of Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Journal of Organic Chemistry (2003), 68(22), 8693-8696, database is CAplus and MEDLINE.

The reaction of mol. bromine (Br₂) with arylthioureas is known to produce 2-aminobenzothiazoles (Hugerschoff reaction). The authors show here that benzyltrimethylammonium tribromide, a stable, crystalline organic ammonium tribromide (OATB), can be readily utilized as an alternative electrophilic bromine source. It is easier to control the stoichiometry of addition with an OATB, which minimizes aromatic bromination caused by excess reagent. The authors have developed a direct procedure from isothiocyanates and amines using tetrabutylammonium thiocyanate (Bu₄NSCN) and PhCH₂NMe₃Br₃ to afford functionalized 2-aminobenzothiazoles.

A facile one-pot method for synthesis of 3,4-dihydroxybenzaldehyde (I) from p-hydroxybenzaldehyde (II) via bromination and hydrolysis in ionic liquid was studied. Under the conditions of the molar ratio of II/ionic liquid 1-butyl-3-methylimidazolium tribromide ([bmim]Br₃) 1:1, reaction temperature 20°, reaction time 30 min and solvent-free, the II was brominated with ionic liquid [bmim]Br₃ to give 3-bramo-4-hydroxybenzaldehyde with 99.7% selectivity; and then without separation, the product of bromination was further hydrolyzed with NaOH aqueous solution in ionic liquid 1-butyl-3-methylimidazolium bromide ([bmim]Br), which is formed from [bmim]Br₃ after the process of bromination, to form I with 84.7% yield and 99.3% purity under the conditions as follows: the NaOH dosage is 1.25 mol/(mol II)^-1, reaction temperature is 100° and reaction time is 2 h. The ionic liquid can be reused at least six times without significant decrease of the yield and purity of I. This method has the advantages of convenience, mild reaction conditions, good yield, high selectivity, solvent-free and environmental friendliness.

In the present work, a series of structurally novel benzocyclobutene derivatives were identified as general anesthetics through the loss of righting reflex (LORR) experiment on mice. Our initial efforts found compound 1a with a fused four-membered ring on the 2,3-position of the phenol ring could significantly improve the safety profile. Further SAR study revealed that small hydrogen bond acceptor (HBA) groups are optimal for good ED₅₀ along with much broader therapeutic windows, such as compounds 16b and 17. Present work demonstrates the superiority of this novel benzocyclobutene scaffold.

The synthesis of fluorene-based p-conjugated polymers via sequential bromination and direct arylation was demonstrated. Bromination of 9,9-dioctylfluorene using BTMA Br3 efficiently proceeded and barely inhibited the following direct arylation polycondensation, successfully giving π-conjugated polymers. This is the first example of the facile synthesis of π-conjugated polymers in a one-pot fashion, without the need for prior preparation and purification of dibrominated aromatic monomers as well as organometallic monomers, and the bromination reaction using BTMA Br3 is also available to other aromatic compounds such as thiophene and carbazole derivatives Therefore, the fundamental step-economical protocol described here should present new insights for the synthesis of π-conjugated semiconducting materials.
