Tetraalkyldibismutane/Tetraalkyldibismutanes

Abstract

The tetraalkyldibismutanes R2BiBiR2 (R = Et, Pr, iPr, Bu) were synthesized by reactions of 1,2-dibromoethane with sodium dialkylbismutides, which were produced by cleavage of the corresponding trialkylbismutanes with sodium in liquid ammonia. The dibismutanes were isolated in good yields as air sensitive red liquids. Spectral data of dibismutanes and some bismutanes are compared with data of their antimony analogues. 1H NMR spectra reveal, that the methylene protons in Et4Bi2 as well as the methyl groups in iPr4Bi2 are diastereotopic.

Keywords: Tetraethyldibismutane; Tetrapropyldibismutane; Tetraisopropyldibismutane; Tetrabutyldibismutane; Triisopropylbismutane
