Reaction Conditions

Reaction Steps

Under argon stream, 3.53 ml (25 mmol) of trimethylsilylacetylene was dissolved in 25 ml of tetrahydrofuran and cooled to -78° C. Into the solution was added dropwise 14.9 ml (24 mmol) of butyllithiumhexane solution, and the reaction was carried out with stirring for 30 minutes. Then, 6.5 ml (24 mmol) of tributyltin chloride was added dropwise, and the reaction was carried out with stirring for 22 hours, while elevating gradually the temperature of the reaction mixture to room temperature. After the reaction, the solvent was evaporated and the residue was distilled under reduced pressure (0.6 mm Hg, 100°-102° C.) to obtain 4.84 g of a transparent liquid (yield: 52.2%).
