In 2013,Dai, Jian-Jun; Fang, Chi; Xiao, Bin; Yi, Jun; Xu, Jun; Liu, Zhao-Jing; Lu, Xi; Liu, Lei; Fu, Yao published 《Copper-Promoted Sandmeyer Trifluoromethylation Reaction》.Journal of the American Chemical Society published the findings.Category: pyridine-derivatives The information in the text is summarized as follows:
A copper-promoted trifluoromethylation reaction of aromatic amines is described. This transformation proceeds smoothly under mild conditions and exhibits good tolerance of many synthetically relevant functional groups. It provides an alternative approach for the synthesis of trifluoromethylated arenes and heteroarenes. It also constitutes a new example of the Sandmeyer reaction. The experimental part of the paper was very detailed, including the reaction process of 6-Bromopyridin-3-amine(cas: 13534-97-9Category: pyridine-derivatives)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. The reaction of alkyl halides, R―X, where X is a halogen, or analogous reagents with ammonia (or amines) is useful with certain compounds. Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones. Its usefulness is largely confined to primary alkyl halides (those having two hydrogen atoms on the reacting site).Category: pyridine-derivatives
