Chemistry of Heterocyclic Compounds Aims and scope

Abstract

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