Ethylenedicyclohexanone and phosphorus pentasulfide give 9-methyloctahydrothioxanthene (II) (yield ∼37%), a small amount of 9-methylperhydrothioxanthene (IV) (∼2%), and 9-methylthioxanthene (VI) (∼1%). Reaction with hydrogen sulfide gives a high yield of thioxanthene II (64–65%). The behavior of II in dehydrogenation over Pd/C, and of II and IV to oxidation are investigated. IR spectrum data are given for II and its sulfone.
