Adducts of organoselenium and -tellurium trichlorides with antimony pentachloride

Article abstract of DOI:10.1021/ic50103a005

The preparation of a series of 1:1 adducts of organoselenium and -tellurium trichlorides with antimony pentachloride is reported. These compounds are colorless or pale yellow moisture-sensitive crystalline solids. The adducts are soluble in CH₂Cl₂, insoluble in nonpolar organic solvents, and rapidly decomposed by donor organic media. The solid-state infrared spectra are interpreted in terms of the formulation [RMCl₂⁺][SbCl₆^-], where M = Se, Te. Proton magnetic resonance data on these compounds are discussed.
