- New Reagents, XXXIII, Synthesis of (Diphenylbismutino)methyllithium and its Reactions with Carbonyl Compounds
-
Bis(diphenylbismutino)methane (3; yield max. 53percent) was synthesized for the first time.By the reaction with phenyllithium it gave (diphenylbismutino)methyllithium (4; ca. 70percent).This thermolabile compound (half-live period ca. 34 min at 25 deg C) reacts at -78 deg C with aldehydes and benzophenone.The adducts are decomposed by HClO4 to give alkenes.Hydrolysis with water of the benzophenone adduct gave 2-(diphenylbismutino)-1,1-diphenylethanol (7; 48percent).

- A Synthesis of Tetramethyldibismuthane and its Cleavage to Bis(dimethylbismuth)oxide or Sulfide and Phenyldimethylbismuthane, Respectively
-
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
