Allyl-allyl or benzyl coupling reactions were effected by allyl carbanions, generated from allyl phenyl selenides and n-butyllithium and allylic or benzylic halides. The ambident selectivities of the allyl carbanions are depending in the solvent system.
烯丙基-烯丙基或苄基偶联反应是由
烯丙基苯基硒和
正丁基锂以及烯丙基或苄基卤化物生成的烯丙基碳离子实现的。烯丙基碳离子的歧化选择性取决于溶剂体系。
