Ionic liquids as benign catalysts for the carbonylation of amines to formamides
摘要:
1-Butyl-3-methylimidazolium hydrogen carbonate ([BMIm][HCO3]), prepared from the reaction of [BMIm]Cl with K2CO3 in methanol, exhibits high activity for the carbonylation of amines to produce formamides.Computational calculation results on the carbonylation reaction of methylamine implies that such high activity of [BMIm][HCO3] could be ascribed to the bi-functional actions of [HCO3](-) as a hydrogen atom acceptor and a donor.

CO2 hydrogenation to formic acid was achieved without consumption of a base and a turnover number of up to 364 249 was obtained. HCOOH is isolatable and the catalyst–base system is easily recycled.
