Abstract
The reaction between dry arenediazonium o-benzenedisulfonimides
(1) 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 (7) was 86% and that
of the S-aryl thiobenzoates (8) 88%. It was possible to recover,
in good amount and from all the reactions, o-benzenedisulfonimide
(9), reusable for the preparation of salts 1.
