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-tetramethylenebicyclononanon-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.

A method of generating light through chemiluminescence involves providing a stable 1,2-dioxetane of the formula: Wherein (a) R1 and R2 are each, individually, a chemical reactive site or when fused together form a chemical reactive site, and R3 and R4 are each, individually, a chemical reactive site or when fused together form a chemical reactive or (b) R1 has at least two hetero atoms with chemical reactive site and R3 and R4 are inactive site and R2 is a chemical reactive site.

The present invention provides novel 1,2-dioxetanes derived from spiro-fused ketones with or without π-electrons in the ring or with carbon-carbon double bond(s) in the spiro-fused ring. Additionally, these new dioxetanes have electron donating or withdrawing groups at the four-membered peroxide ring to render these dioxetanes active at all sites.
