실험 절차

4.1 ml of the tetrahydrofuran solution of magnesium 2-(1,3-butadienyl)chloride and 6 ml of dried tetrahydrofuran were charged into a reactor in the stream of argon. Subsequently, the reactor was cooled down to 0° C., followed by gentle dropping of 1.2 ml (8 mmols) of tetramethoxysilane. While the reaction temperature was kept at 0° C., the reaction was continued for 30 minutes. After completion of the reaction, the solvent was distilled off to obtain 2-(trimethoxy)silyl-1,3-butadiene (yield: 65%).
