Sodium dimethylbismuthide, generated from dimethylbismuth bromide and sodium in liquid ammonia, was treated with alkyl halides to produce dimethylalkylbismuthanes, Me2Bi(alk) (alk = C2H5, n-C3H7, n-C4H9, C3H5, i-C3H7) as thermolabile liquids in yields ranging from 70 to 90percent.With methylene chloride bis(dimethylbismutho)methane, (Me2Bi)2CH2, was obtained.Aryldimethylbismuthanes, (aryl)BiMe2, were prepared by treating dimethylbismuth bromide in THF with elemental lithium (-78 deg C) and subsequent reaction with aryl halides (aryl = 4-C6H4CH3, 4-C6H4OCH3, 2,4,6-C6H2(CH3)3).At 90 deg C in an N2-stream, the thermolabile compounds react quantitatively to form diarylmethylbismuthanes, (aryl)2BiMe and Me3Bi. - Keywords: Dimethylalkylbismuthanes, Bis(dimethylbismutho)methane, Aryldimethylbismuthanes, Diarylmethylbismuthanes

Tetramethyldibismuthane, Me4Bi2 was prepared in high yields by reducing Me2BiBr with sodium in liquid ammonia.The compound reacts quantitatively with equimolar amounts of oxygen or sulfur to yield the corresponding (Me2Bi)2O and (Me2Bi)2S.By cleavage of Me4Bi2 with PhLi, PhBiMe2 was obtained; the latter is also available in better yields by the reaction of Me2BiBr with PhLi. - Key words: Tetramethyldibismuthane, Bis(dimethylbismuth)oxide, Bis(dimethylbismuth)sulfide, Phenyldimethylbismuthane, Lithiumdimethylbismuthane
