selective direct reductive amination of aldehydes with primary and secondary amines in water using gaseous hydrogen and water-soluble catalysts is developed. The catalytic system formed in situ from Pd(PhCN)2Cl2 and 2,2′-biquinoline-4,4′-dicarboxylic acid dipotassium salt (BQC), allows full conversion of aldehydes and the formation of desired alkylated amines with excellent yields and selectivities
开发了一种空前的高效,高选择性,使用气态氢和水溶性催化剂的水中的醛与伯胺和仲胺直接还原胺化方法。由Pd(PhCN)2 Cl 2和2,2'-联喹啉-4,4'-二羧酸二钾盐(BQC)原位形成的催化系统可实现醛的完全转化并以优异的收率形成所需的烷基化胺和选择性。该催化体系是稳定的,可以循环使用三遍而不会失去活性。
