UsesN-Benzylmaleimide is used as plastic additive, Pharmaceutical Intermediates. It is an important raw material intermediate used in organic Synthesis, Pharmaceuticals, Agrochemicals Dyestuff.

General DescriptionN-Benzylmaleimide is an N-substituted maleimide and its microwave-mediated facile and fast synthesis has been described. Radical and anionic copolymerization of N-benzylmaleimide with optically active N-(L-menthoxycarbonylmethyl)maleimide has been reported. Base-catalyzed asymmetric cycloaddition of anthrone with N-benzylmaleimide was studied in the presence of C2-chiral pyrrolidines. Stereoselctive iridium-catalyzed double incorporation reaction of styrene with N-benzylmaleimide affords cyclic product.
