A practical zinc acetate dihydrate‐catalyzed reductive amination of various carbonyl compounds with N,N‐dimethylformamide (DMF) as dimethylamino (Me₂N) source, reductant and solvent has been developed. This reaction shows broad substrate scope, good functional group tolerance, avoids the need for a pressure‐proof reactor and column chromatographic isolation operations and gives up to 98% yield, to make it an attractive method for the preparation of tertiary N,N‐dimethylamines.

N，N-二甲基甲酰胺为二甲氨基源，还原剂和溶剂的路易斯酸催化醛和酮的还原胺化

已经开发了一种实用的乙酸锌二水合物催化的羰基化合物以N，N-二甲基甲酰胺（DMF）作为二甲基氨基（Me ₂ N）来源，还原剂和溶剂的还原胺化方法。该反应显示出广泛的底物范围，良好的官能团耐受性，无需耐压反应器和色谱柱色谱分离操作，且收率高达98％，使其成为制备N，N-二甲基叔胺的有吸引力的方法。
