Fractional recrystallization of diastereoisomeric phenyl>(methyl)selenonium 4,4-dimethyl-2,6-dioxocyclohexylide from hexane-diethyl ether gave the optically pure (+)-selenonium ylide as stable crystals.The absoute configuration around the selenium atom was determined to be R by X-ray crystallographic analysis.The epimerization of the optically active selenonium ylide by pyramidal inversion was studied.
