Dimethyl(phenylchalkogeno)bismutane — Moleküle mit Bismut-Schwefel, -Selen und -Tellur-Bindungen / Dimethyl(phenylchalcogeno)bismuthanes — Molecules with Bismuth-Sulfur, -Selenium and -Tellurium Bonds

Abstract

Dimethyl(phenylchalcogeno)bismuthanes of the general formula (CH 3 ) 2 BiEC 6 H 5 (E = S, Se, Te), the first m olecules with a Bi -Se or a Bi-Te-bond, respectively, were synthesized in good yields by reactions of tetramethyldibismuthane and diphenyldichalcogenides. At room temperature - these thermolabile compounds react quantitatively - with increasing rate in the series S-Se-Te to give CH 3 Bi(EC 6 H 5 ) 2 and Bi(CH 3 ) 3 .
