Abstract: A process for producing N-acyl-2-pyrrolidone which comprises contacting N-acyl allylamine with carbon monoxide in the presence of an aliphatic carboxylic acid solvent and a homogeneous catalyst of palladium or platinum coordinated with triphenylphosphine. According to a preferred embodiment, the acyl group is removed from the N-acyl-2-pyrrolidone by contacting and heating the N-acyl-2-pyrrolidone with allylamine to thereby effect transacylation and obtain product 2-pyrrolidone and N-acyl-allylamine as a recycle feed stream. Alternatively, N-acyl-2-pyrrolidone can be hydrolyzed to 2-pyrrolidone and the carboxylic acid derived from the acyl group.
