| Abstract: | The reductive amination in ionic liquids was researched. The results show that the aromatic aldehydes and amines continuously process the condensation reaction and the reduction reaction to afford the corresponding secondary amines with high yield (70%~98%). NaBH4 in BMImBF4 is found to be an efficient system for the reductive amination with good reductive ability and excellent selectivity. The advantages of the reaction in above system are its mild and neutral reactive conditions. Furthermore BMImBF4 could be reused for at least 12 times. |
