Alcoholysis of acylâPd(II) complexes relevant to palladium catalysed CO/ethene coupling reactions such as polyketone synthesis/alkoxycarbonylation reactions is shown, in a highly active catalyst system, to proceed via coordination of methanol to the Pd centre prior to nucleophilic attack at the acyl carbon.

乙烯偶联反应(例如聚酮合成/烷氧基羰基化反应)相关的酰基-Pd(II)络合物的醇解显示,在高活性催化剂体系中,通过在亲核攻击之前将
甲醇配位到 Pd 中心来进行在酰基碳上。
