A practical zinc acetate dihydrate‐catalyzedreductiveamination 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
