Abstract
On reaction with Grignard compounds, sym-octahydrothioxanthylium and 9-methyl-symoctahydrothioxanthylium perchlorates form 9-mono- and 9, 9-disubstituted sym-octahydrothioxanthenes. The reactions of the new sym-octahydrothioxanthene with perchloric acid and ferric chloride has been studied. The elimination of the benzyl group of 9-benzyl-sym-octahydrothioxanthene on salt formation has been observed.
