Procedure

As in Example 1, 1,3-hexadiene (0.99 g, 12.06 mmol), trichlorosilane (6.60 g, 48.73 mmol) and tetrabutylphosphonium iodide (0.47 g, 1.22 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 10 hours. The resulting mixture was distilled to yield 1.32 g (yield: 60%) of 1,1-dichloro-2,5-dimethyl-silacyclo-3-pentene and 0.43 g (yield: 10%) of 2,5-bis(trichlorosilyl)-3-hexene main products.
