摘要
Palladium-catalyzed amination of 3-bromopyridine with amines of the adamantane series in the presence of Pd(dba)(2)/L [L = 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl or 2-dimethylamino-2'-dicyclohexylphosphinobiphenyl] gave the desired N-(pyridin-3-yl)-substituted amines in 74-97% yields. Diamines of the adamantane series reacted with 2 equiv of 3-bromopyridine in a complicated fashion to produce mono- and triaryl-substituted derivatives as by-products, while the yields of N,N'-diarylation products were 18-56%.
