Four grams (41×1.5 mmols) of Zn powder and 15 ml of THF were added, under agitation, to 10 g (41 mmols) of the 1,4-dichloro-2-(trimethoxy)silyl-2-butene obtained by the above procedure. The mixed solution was heated and refluxed for 1 hour and then cooled down to room temperature, followed by adding 30 ml of dried pentane. The resulting ZnCl2 was removed by filtration and the solvent was distilled off under reduced pressure, followed by vacuum distillation to obtain 5.0 g of 2-(trimethoxy) silyl-1,3-butadiene.
