Abstract

original image

A broad range of amides is accessible in excellent yield (>99 %) by hydration of the corresponding nitriles in water in the presence of the supported ruthenium catalyst Ru(OH)x/Al2O3 (see scheme). For example, the industrially important conversion of acrylonitrile into acrylamide was achieved in quantitative yield and better than 99 % selectivity. The catalyst can be reused without loss of catalytic activity and selectivity.
