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 with Grignard reagents.
银盐催化有机锌试剂对叔烷基溴化物的苄基化和烯丙基化反应。这些反应有效地生成了季碳原子中心。在银催化下，用苄基或烯丙基锌试剂处理偕二溴烷烃，可得到二苄基或二烯丙基产物。与之前用格氏试剂进行的反应相比，本反应的官能团兼容性更广泛。
