Photochemical reactions of naphthodithiole-3-thione (7), naphthodithiole-1-thione (10), and naphthodithiole-3-thione (16) with cyclohexene and 2,3-dimethyl-2-butene afford the corresponding naphthothioquinone methides.The thioquinone methide from 7 exists only as a monomeric form and is the first isolable o-thioquinone methide, while that from 16 exists as a dimer of type in the solid state although the chemical behavior suggests the presence of a monomeric form in solution to a very minor extent.In the case of the thioquinone methide from 10, there exists an equilibrium between a monomer and a dimer of type.Some cycloadditions of these thioquinone methides are also described.
