Treatment of alkyl halides, including tertiary alkyl bromides, with benzylic or allylic Grignard reagent in the presence of a catalytic amount of silver nitrate in ether yielded the corresponding cross-coupling products in high yields. The coupling reactions of tertiary alkyl halides provide efficient access to quaternary carbon centers.
在醚中催化量的硝酸银存在下,用苄基或烯丙基格氏试剂处理卤代烷,包括叔烷基溴化物,可以高产率得到相应的交叉偶联产物。叔烷基卤化物的偶联反应提供了到季碳中心的有效通道。
