Abstract

A one-step process for the preparation of N-substituted (meth)acrylamides from the reaction of a (meth)acrylate ester and an amine over a catalytic amount of a metal alkoxide catalyst is described. These catalysts, such as stannous dimethoxide, lead dimethoxide, zinc dimethoxide, copper dimethoxide and bismuth tributoxide give high selectivity to the N-substituted (meth)acrylamides and little selectivity of the Michael adduct propionate ester, which would predominate in the absence of these catalysts. Also, these catalysts are less costly than organo metal catalysts commonly used.
