ABSTRACT:
Cyclic imides are prepared by reacting carbon monoxide with an ortho dihalide aromatic compound or a cis-1,2-vinyl dihalide and an amine in the presence of palladium catalyst and a base. The process is preferably conducted in the presence of a dipolar aprotic solvent as a liquid reaction medium.
Acyclic imides are prepared by reacting CO with an activated halide and an amide (primary or secondary) in the presence of a Pd catalyst and a base.
