2,3-Dichloro-N-phenylmaleimide 2 undergoes nucleophilic substitution reactions by a variety of nucleophiles giving either monosubstituted 5 or disubstituted 3 products. Treatment of 5 with sodium azide at room temperature results in cyclization to the corresponding 2-phenylpyrrolo[3,4- b]quinoxaline-1,3-diones 6, while at higher temperatures 5 is reduced to the 2-amino-amino-N-phenylmaleimides 7.

Quinoxaline- and indole-2,3-dicarboxylic imides 7,8 are prepared by reaction of halogenactive maleimides 1,2 with sodium azide.Further derivatives of these heterocyclic series are available by secondary reactions of the imides.
