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.
四氯化钛催化的芳香醛与(二烷基氨基)二甲基硅烷反应,能以中等至高产率得到叔胺。脂肪醛的还原胺化反应也受到ZnI2的有效催化。在存在Ph3CClO4的情况下,甲基N-(二甲基硅基)氨基甲酸酯同样可用于羰基化合物的还原胺化。
