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.
