Abstract

Reasons are given for the formation of two different products from the chlorination of saccharin with phosphorus pentachloride: initially 2-chlorosulfonylcyanobenzene is formed which, under appropriate conditions, cyclises to give 3-chloro-1,2-benzisothiazole 1,1-dioxide, an important derivatising agent for alcohols.
