(MPV)-type reduction between benzonitriles and benzylic alcohols under transition-metal-free conditions has been demonstrated for the first time. Using simple KOt-Bu as the base, various benzonitriles can be efficiently reduced by benzylic alcohols via hydrogen transfer reduction, and the resultant phenyl imine can react further with benzylic alcohols to give amides as the final product in which both
Meerwein-Ponndorf-Verley (MPV) 型在无过渡金属条件下苯甲腈和苯甲醇之间的还原首次得到证实。以简单的 KO t -Bu 为碱,苯甲醇可以通过氢转移还原有效地还原各种苯甲腈,生成的苯亚胺可以与苯甲醇进一步反应得到酰胺作为最终产物,其中醇和腈均被纳入。初步机理研究表明,该反应可能经历多个 MPV 型氢转移过程。
