Shi, Lan-xiang; Zhang, Bao-hua; Zhang, Xing-chen published the artcile< Synthesis of 4-bromo-N,N-dimethylaniline>, Quality Control of 112-63-0, the main research area is bromo dimethylaniline preparation pyridinium tribromide.
A method for the synthesis of the title compound is reported here. In presence of pyridine, 4-bromo-N,N-dimethylaniline was synthesized by a substitution reaction starting from N,N-dimethylaniline and bromine. In this reaction, the easy-to-handle bromination agent pyridinium tribromide was formed and the regioselectivity of the substitution reaction was enhanced. The optimal molar ratio was n(C8H11N):n(Br2):n(C5H5N) = 1:1.1:1.1, the reaction was at 10-15° for 6 h (product yield 68%).
Hebei Shifan Daxue Xuebao, Ziran Kexueban published new progress about Bromination, regioselective. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Quality Control of 112-63-0.
