Synthesis Example 4 (Synthesis of Trimethylbismuthane) Under argon gas atmosphere, a solution of 25 g of bismuth tribromide in 40 ml of THF was added dropwise to a 1.0 M diethyl ether solution of methyllithium to keep reflux. Thereafter, the mixture was stirred at room temperature for 1.5 hours. The solvent was evaporated under atmospheric pressure, followed by the distillation of the desired compound. The obtained distillate was distilled again, giving 8.1 g of colorless oily material (54.8% in yield). It was confirmed that the product was the desired one by ¹H-NMR. ¹H-NMR (300 MHz, CDCl₃) 1.13 (s, 9H)
