Abstract
Di‐(alk‐1‐ynyl) thioethers IV have been prepared from 2,2′‐dichlorodivinyl thioether II by converting this compound into metallated diethynyl thioether by means of four equivalents of sodamide in liquid ammonia, followed by alkylation. The starting material II was obtained in a high yield by partial dehydrochlorination of the adduct I from vinyl chloride and sulphur dichloride. The overall yields are very satisfactory.
