Oxidative heterocoupling between two Grignard reagents RMgX and R′MgX is made possible by manganese catalysis with O2 as an oxidant. This procedure, development of which was based on mechanistic analysis of the corresponding homocoupling reaction, can be steered towards the heterocoupling product at the expense of the homocoupling products by judicious choice of the R and R′ groups (see examples).
通过以O 2为氧化剂的锰催化,可以实现两种格氏试剂RMgX和R'MgX之间的氧化杂化。该方法的开发是基于对相应的均偶联反应的机理分析,可以通过明智地选择R和R'基团,以牺牲均偶联产物为导向,转向异偶联产物(参见示例)。
