A simple and convenient procedure for direct reductive amination of aldehydes and ketones with sodium borohydride is described. The reaction has been carried out in methanol in the presence of a catalytic amount of H3PW12O40 (0.5 mol %). α,β-Unsaturated aldehydes and ketones can be easily converted into the corresponding allylalcohols by reaction with H3PW12O40 (0.5 mol %)/NaBH4.

Lewis Acid-Catalyzed Reductive Amination of Carbonyl Compounds with Aminohydrosilanes
The TiCl4-catalyzed reaction of aromatic carbonyl compounds with (dialkylamino)dimethylsilanes gave tertiary amines in moderate to high yields. The reductive amination of aliphatic aldehydes was effectively catalyzed by ZnI2. Methyl N-(dimethylsilyl)carbamate as well could be used for reductive amination of carbonyl compounds in the presence of Ph3CClO4.

Dialkylformamides are excellent N-sources in the amination of benzylchlorides when catalysed by a NHC-Pd(II)-Im complex. In the presence of NaOH and the catalyst, variously substituted benzylchlorides and five different dialkylformamides reacted smoothly to afford the corresponding N,N-dialkyl-benzylamines in good to almost quantitative yields in eco-friendly solvent water at 50 °C within 3 h.
