An anionic iron complex catalyzes the decarboxylative allylation of phenols to form allylic ethers in high yield. The allylation is regioselective rather than regiospecific. This suggests that the allylation proceeds through π-allyl iron intermediates in contrast to related allylations of carbon nucleophiles that have been proposed to proceed via σ-allyl complexes. Ultimately, iron catalysts have the
阴离子铁络合物以高收率催化酚类的脱羧烯丙基化反应,形成烯丙基醚。烯丙基化是区域选择性的而不是区域特异性的。这表明烯丙基化是通过π-烯丙基铁中间体进行的,与碳亲核试剂的相关烯丙基化相反,后者已提议通过σ-烯丙基络合物进行。最终,铁催化剂具有取代通常用于脱羧偶联的更昂贵的钯催化剂的潜力。
