2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Formula: C9H11Br

Asymmetric phase-transfer catalysis of homo- and heterochiral quaternary ammonium salts: development and application of conformationally flexible chiral phase-transfer catalysts was written by Ooi, Takashi;Uematsu, Yukitaka;Kameda, Minoru;Maruoka, Keiji. And the article was included in Tetrahedron in 2006.Formula: C9H11Br This article mentions the following:

Inspired by the considerable difference of catalytic activity and stereocontrolling ability between the conformationally rigid, homo- and heterochiral quaternary ammonium bromides 1 (I), conformationally flexible, N-spiro chiral quaternary ammonium bromides of type 4 (II) have been designed and synthesized. Reliable procedures for the preparation of the appropriately substituted biphenyl subunits have been established by the repeated use of ortho magnesiation-halogenation as a key synthetic tool. The relationship between the structure of achiral biphenyl moiety and the reactivity and selectivity of 4 has been evaluated in the asym. alkylation of glycinate Schiff base 2 (III) under typical phase-transfer conditions, leading to the identification of 4l (Ar1 = 3,5,-Ph2-C6H3) as an optimal catalyst structure to exhibit an excellent enantiocontrol in the reactions with various alkyl halides. The mol. structure of 4l was determined by X-ray crystallog. anal. and its unique behavior in solution was examined by a variable-temperature 1H NMR study. These investigations uncovered that the observed high chiral efficiency originated from the efficient asym. phase-transfer catalysis of homochiral-4l, which rapidly equilibrated with heterochiral-4l of low catalytic activity and stereoselectivity. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7Formula: C9H11Br).
