Acetylenes were stereoselectively brominated with molecular bromine adsorbed on graphite in dichloromethane to produce (E)-α,β-dibromoalkenes; isomerization of the E-isomer to the Z-isomer, usually catalyzed by bromine, did not occur in the presence of graphite.
乙炔在二氯甲烷中与吸附在石墨上的分子溴进行立体选择性溴化,生成 (E)-α,β-二溴烯烃;E-异构体异构化为 Z-异构体,通常由溴催化,在石墨存在下不会发生。
