Abstract

The reaction between dry arenediazonium o-benzenedi­sulfonimides and sodium thioacetate or thiobenzoate in anhydrous acetonitrile at room temperature is an efficient and safe procedure, of general validity, for the preparation of S-aryl thiol esters. The products can be easily purified and the yields are always very high. Of the 28 considered examples, the average yield of the S-aryl thioacetates was 86% and that of the S-aryl thiobenzoates 88%. It was possible to recover, in good amount and from all the reactions, o-benzenedisulfonimide, reusable for the preparation of arenediazonium salts.
