reaction: A highly efficient PdII‐catalyzed intermolecular oxidative‐coupling reaction is reported, inspired by the fundamental Heck and Wacker processes. The (hetero)aryl‐PdX species, originating from CH activation step or desulfonyl hydrazides, coupled with allylic alcohols by using oxygen as the sole oxidant (see scheme).
Wacker的反应:受基本的Heck和Wacker过程的启发,据报道有一种高效的Pd II催化的分子间氧化偶联反应。(杂)芳基- PDX物种,选自C始发 ħ活化步骤或desulfonyl酰肼,通过使用氧作为唯一的氧化剂(参见方案)加上烯丙基醇。
