18. 4-Thiomethyl styrene was prepared in two steps from commercial 4-vinylbenzylchloride, first by displacement of the chloride by using potassium thioacetate in dimethylacetamide, followed by hydrolysis in aqueous KOH to give the free thiol. This procedure was adapted from that found in the patent literature: Dow Chemical Co.; US 2947731; 1960.
