在室温下，以O-2为末端氧化剂，烯丙基C-C双键辅助下，钯催化芳烃选择性邻烯烃化。提出了丙烯基C=C键与Pd初始配位后选择性o-C-H键金属化的可能机理。
Pd-catalyzed selective ortho-olefination of arenes assisted by an allylic C-C double bond at room temperature using O-2 as a terminal oxidant is described. A possible mechanism involving the initial coordination of allylic C=C bond to Pd followed by selective o-C-H bond metalation is proposed.
