Lithium bismuthide

A number of compounds of the types RBiY2 or R2BiY, where Y is an anionic group other than halogen, have been prepared by the reaction of a dihalo- or halobismuthine with a lithium, sodium, potassium, ammonium, silver, or lead alkoxide (120,121), amide (122,123), a2ide (124,125), carboxylate (121,126), cyanide (125,127), dithiocarbamate (128,129), mercaptide (130,131), nitrate (108), phenoxide (120), selenocyanate (125), silanolate (132), thiocyanate (125,127), or xanthate (133). Dialkyl- and diaryUialobismuthines can also be readily converted to secondary bismuthides by treatment with an alkali metal (50,105,134) ...

A solution of lithium bis(trimethylsilyl)bismuthide-2 THF (25.3 g, 50 mmol) in pentane (100 ml) was added slowly to a cooled (-30°C) solution of 1,2-dibromoethane (4.7 g, 25 mmol) in the same solvent (100 ml). As the reaction proceeded, lithium bromide precipitated from a yellowish orange reaction mixture. Liberated ethylene gas (24.6 mmol) was collected into an inverted stand cylinder above water. After completion of the reaction, the precipitate was filtered off and washed successively with pentane. The volatiles were distilled off in vacuo at 20°C to leave a solid residue, which was recrystallized from pentane. The yield was 13.5 g (76%) [82ZN(B)91],...
