The selenoxides forming 9-oxoselenoxanthenium and triaryl selenonium hexafluorophosphates via interaction with heptyl phenyl ether and anisole in the MeSO3H-P2O5 mixture followed by treatment with KPF6 have been obtained via selenoxantene-9-one and diphenyl selenide derivatives oxidation with m-chloroperoxybenzoic acid or hydrogen peroxide.

Selenoxanthen 10-oxides (5a-d) reacted with methyl propiolate, dimethyl and diethyl acetylenedicarboxylates to afford selenoxanthen-10-iometanides (6a-i).The 9-isopropyl derivative gave only trans-ylides and the 9-phenyl congener formed cis- and trans-ylides.The stereochemistry is discussed on the basis of the nuclear magnetic resonance spectral data.Reduction of the selenoxanthenium ylides with sodium borohydride afforded the ylide lactones (16a-c) and the ylide alcohols (17a-f).The Product ratio depended on the solvent used.Keywords - selenium ylide; selenoxide; selenoxanthene; methyl propiolate; dimethyl acetylenedicarboxylate; stereoisomer; stereochemistry; sodium borohydride reduction; lactonization

The adducts of chlorine with diaryl selenides such as selenanthrene, diphenyl selenide, and selenoxanthone have been found to be reduced to the corresponding selenides in dimethyl sulfoxide forming chloromethyl methyl sulfoxide and hydrogen chloride.Similarly, dimethyl selenide dichloride was reduced to dimethyl selenide in the presence of a base.
