Procedure
As in Example 1, 1,3-cyclooctadiene (1.00 g, 9.24 mmol), trichlorosilane (5.01 g, 36.99 mmol) and tetrabutylphosphonium chloride (0.27 g, 0.92 mmol) were added in a 25 mL stainless steel tube under nitrogen atmosphere. After sealing the cylinder with a cap, the reactor was maintained at 180° C. for 20 hours. The resulting mixture was distilled to yield 0.35 g (yield: 10%) of 2,7-bis(trichlorosilyl)-1-octene.
