The use of the Pd(dba)12/dpe catalytic system in allylic alkylation allows sodium dimethyl malonate to react with allylic acetates at room temperature. According to this procedure, a novel synthesis of allylic substituted cyclopentadienes is described through the use of cyclopentadienide anion as a nucleophile.
在烯丙基烷基化中使用Pd(dba)1 2 / dpe催化体系可使丙二酸二甲酯钠在室温下与乙酸烯丙酯反应。根据该方法,描述了通过使用环戊二烯阴离子作为亲核试剂来合成烯丙基取代的环戊二烯的新方法。
