2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Application In Synthesis of 2-(Bromomethyl)-1,3-dimethylbenzene

Design of N-Spiro C2-Symmetric Chiral Quaternary Ammonium Bromides as Novel Chiral Phase-Transfer Catalysts: Synthesis and Application to Practical Asymmetric Synthesis of α-Amino Acids was written by Ooi, Takashi;Kameda, Minoru;Maruoka, Keiji. And the article was included in Journal of the American Chemical Society in 2003.Application In Synthesis of 2-(Bromomethyl)-1,3-dimethylbenzene This article mentions the following:

Chiral phase-transfer catalysts, C2-sym. chiral quaternary ammonium bromides I (Ar = Ph, α-naphthyl) and II [Ar = H, Ph, β-naphthyl, 3,5-(diphenyl)phenyl, 4-fluorophenyl, 3,4,5-trifluorophenyl], were readily prepared from com. available optically pure 1,1′-bi-2-naphthol. Detailed procedures for the synthesis of I and II were given, and the structures of II (Ar = H, 3,4,5-trifluorophenyl) were unequivocally determined by single-crystal x-ray diffraction anal. The reactivity and selectivity of these chiral ammonium bromides as chiral phase-transfer catalysts were evaluated in the asym. alkylation of Ph2C:NCH2CO2R (R = Bu-t, Me, CH2Ph, CHPh2) by PhCH2Br under mild liquid-liquid phase-transfer conditions, and the optimization of the reaction variables (solvent, base, and temperature) was conducted. In addition, the scope and limitations of this asym. alkylation were thoroughly investigated with a variety of alkyl halides, in which the advantage of the unique N-spiro structure of II and dramatic effect of the steric as well as the electronic properties of the aromatic substituents on the 3,3′-position of the binaphthyl moiety were emphasized. Finally, the asym. synthesis of Me and tert-Bu (S)-N-acetylindoline-2-carboxylates, and L-Dopa (L-3,4-dihydroxyphenylalanine) tert-Bu ester was successfully accomplished using the above methodol. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7Application In Synthesis of 2-(Bromomethyl)-1,3-dimethylbenzene).
