Bis(2-oxocyclohexyl)methane reacts with hydrogen selenide in polar solvents without a catalyst to give a product of nucleophilic addition of hydrogen selenide at one of the carbonyl groups, which exists in the form of three equilibrium forms, viz., 2-hemolselenolcyclohexyl-2-cyclohexanonylmethane, perhydroselenoxanthene-11,13-diol, and perhydro-11-xanthenol-13-selenol.The latter under the influence of an alcohol solution of alkali form 2,3-tetramethylenebicyclo<3.3.1>nonanon-9-ol, with hydrogen chloride; they react with hydrogen chloride to give sym-octahydroselenoxanthene, and trifluoroacetic acid converts them to a mixture of sym-octahydroselenoxanthylium trifluoroacetate and perhydroselenoxanthene.The trifluoro acetate reacts with perchloric acid to give sym-octahydroselenoxanthylium perchlorate.
