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
