Hydrogenation of C=C bond and reductive amination are important transformations utilized in chemistry. An environmentally friendly, efficient, and facile one-pot transfer hydrogenation of C=C bond of enones and reductive amination of C=N bond of imines are reported using iridium complex as catalysts and formic acid as hydrogen source in aqueous medium. In this catalytic system, a wide range of α-alkylated
C = C键的加氢和还原胺化是化学中重要的转变。据报道,使用铱络合物作为催化剂,甲酸为氢源,在水性介质中,对烯酮的C = C键进行环境友好,高效,便捷的一锅转移加氢和亚胺的C = N键还原胺化。在该催化体系中,通过C = C键的一锅转移加氢和还原胺化,可以以优异的收率获得各种α-烷基胺。该协议的实际应用以克级转换为特征。
