Reaction Steps

While 3.5 g (35×1.5 mmols) of Zn powder and 15 ml of THF were agitated, 8.0 g (35 mmols) of 1,4-dichloro-2-(dimethoxymethyl)silyl-2-butene was added. The mixture was heated under reflux for 2 hours, and then treated in the same manner as in Example 1 to obtain 3.9 g of 2-(dimethoxymethyl)silyl-1,3-butadiene.
