We describe the PdII‐catalyzed decarboxylative Heck reaction of aromatic carboxylic acids with an array of electronically unbiased olefins, which leads to the regioselective formation of less common branched products in good yield. The use of inexpensive, stable, and readily available aromatic carboxylic acids as aryl reagents, make this method attractive for the synthesis of useful α‐alkyl vinylarenes
我们描述了芳族羧酸与一系列电子无偏烯烃的Pd II催化的脱羧Heck反应,这导致了不常见的支化产物的区域选择性形成,收率很高。使用廉价,稳定且易于获得的芳族羧酸作为芳基试剂,使该方法对合成有用的α-烷基乙烯基芳烃具有吸引力。
