The photochemical reactions of benzothiazole-2-thiones in the presence of alkenes have been examined.Irradiation of N-unsubstituted benzothiazole-2-thione in the presence of electron-poor alkenes gave 2-substituted benzothiazoles.Irradiation of N-substituted benzothiazole-2-thiones and electron-poor alkenes yielded 2-alkylidenebenzothiazoles and the unexpected spiro-1,3-dithianes.The formation of these photoproducts can be explained in terms of the intermediacy of amino-spirothietanes, which are derived by photocycloaddition of the C=S bond of benzothiazole-2-thiones to the C=C bond of alkenes.
