Reduction of propargyl S-thioacetate, followed by elimination of excess hydride and acidification, constitutes a practical alternative for the preparation of propargylthiol (as a solution of easily determined concentration) or of its derivatives (by trapping the intermediate thiolate with a suitable electrophile).

Propargylthiol and its derivatives are easily obtained through the hydride-mediated reduction of propargyl thioacetate
