Silver salts catalyze the benzylation and allylation of tertiary alkyl bromides with organozinc reagents. The reactions create quaternary carbon centers efficiently. Treatment of gem‐dibromoalkanes with benzylic or allylic zinc reagents under silver catalysis leads to dibenzylation or diallylation. The functional‐group compatibility of the present reactions is wider than that of the previous reactions
银盐用有机锌试剂催化叔烷基溴化物的苄基化和烯丙基化。该反应有效地产生季碳中心。在银催化下用苄基或烯丙基锌试剂处理宝石二溴代烷烃会导致二苄基化或二烯丙基化。当前反应的官能团相容性比以前使用格氏试剂的反应要宽。
