Reaction of benzothiazol-2-thione and benzothiazol-2-one with acetylene in the presence of potassium hydroxide or cadmium acetate gives 2-vinylthiobenzothiazole and 3-vinylbenzothiazol-2-one, respectively.Benzothiazol-2-thione is partially converted to benzothiazol-2-one by the action of Cd(OAc)2.Under vinylation conditions the latter also forms 2-vinylthioaniline.
