The cooperative catalysis of CpRu(PPh3)2(CH3CN)PF6
(1b) and DBU enables chemoselective nucleophilic activation of acetonitrile in the presence of base-sensitive aldehydes 2 to afford corresponding β-hydroxynitriles 3 in good yield.
CpRu(PPh3)2(CH3CN)PF6 (1b)与
DBU的协同催化作用,能够在存在对碱敏感的醛2的情况下,以良好的产率实现
乙腈的选择性亲核活化,从而得到相应的β-羟基腈3。
