A convenient two-stage method has been developed for preparing benz[d]isothiazol-3(2H)-ones from 2-bromobenzamides and sulfur in a one-pot process under copper catalysis conditions. The method is suitable for the synthesis of N-aryl-, benzyl-, and alkyl-substituted benzisothiazolones. The yields of the benzisothiazolones depend on the nature of the starting amide and can reach 91%.
