Process for preparing organic sulphides

Abstract From the Canadian patent

A process for preparing organic thioethers of formula R-S-R1 in which R is an aliphatic, aryl arylalipllatic or, heterocyclic radical anti R1 is an aliphatic or arylaliphatic radical, from organic dithiocarbonates and organic halides or sulphonates, in the presence of an aqueous alkaline base and a phase transfer catalyst at a temperatu-, re of between 50° and 100°C for a time of 10-60 minutes. The process allows the preparation of large classes of products used as dyestuff and pharmaceutical intermediates and as pesticides herbicides, oxidation inhibitors lubri-, cating oil additives and the like.
