Reaction Steps

In 400 ml of THF was dissolved 22.014 g (50 mmol) of triphenylbismuthine (Tokyo Kasei Co., Ltd.) under nitrogen atmosphere. The solution was cooled to 0° C. and thereto was slowly added dropwise 11.231 g (25 mmol) of tribromobismuthine (Aldrich Corp.) (30 minutes). The mixture was stirred to room temperature for 1 hour. The yellow precipitate was filtered and dried in a vacuum. The obtained precipitate was recrystallized from benzene, giving 27.422 g (62 mmol: yield 83%) of yellow powdery product.
