Treatment of N ‐aryl‐2‐(benzylthio)benzamides with phenyliodine(III) bis(trifluoroacetate) containing trifluoroacetic acid resulted in an interrupted Pummerer‐type reaction in ionic liquid 1‐ n ‐butyl‐3‐methylimidazolium hexafluorophosphate, [bmim][PF 6 ] to give 2‐aryl‐1,2‐benzisothiazol‐3(2 H )‐ones rather than the normal Pummerer‐type products.
