A novel catalytic hydrogen‐autotransfer protocol for the atom‐efficient α‐alkylation of ketones with readily available alcohols is presented. The use of manganese complexes bearing non‐innocent PNP pincer ligands enabled the functionalization of a broad range of valuable ketones, including 2‐oxindole, estrone 3‐methyl ether, and testosterone. Mechanistic investigations suggest the participation of
提出了一种新颖的催化氢自动转移方案,用于用容易获得的醇对酮进行原子有效的α-烷基化反应。使用带有非纯正PNP钳位配体的锰配合物,可以使各种有价值的酮官能化,包括2-氧吲哚,雌酮3-甲基醚和睾丸酮。机理研究表明,分子内酰胺辅助酒精脱氢过程的参与。
