    Abstract: The present invention provides a novel method for the preparation of N-azidosulfonyl-arylimides, which are known as photo-initiators. At the outset, substitution reaction of 4-acetamidobenzenesulfonyl halide with MN3 (M denotes hydrogen or alkaline metal) provides the corresponding azide. After de-protection to remove the actyl group, aminoarylsulfonyl azide is extracted with organic solvent, and the extract is directly used for addition reaction with maleic anhydride without concentration. Finally, end products are obtained by dehydration of the addition products using acetic anhydride/metal acetate, followed by re-crystallization in alcohol solvent. The end products are obtained in purer form and greater yield than that in conventional methods.
