Abstract
It was found that the reactions of N-benzylmaleimide with secondary amines proceed at the double C=C bond and lead to the formation of 3-N,N-R2-aminosubstituted succinimides. In the case of N-phenethylmaleimide, the nucleophilic addition of secondary amines is accompanied by an amidation reaction, which proceeds with ring opening and leads to the formation of unsymmetrical maleic acid diamides.
