Procedure

In another experiment, 220 g (1.62 mole) trichlorosilane was added slowly in 20 minutes to a stirred mixture of 660 g (6 mole) 1,7-octadiene at 35° C. Subsequently, the reaction mixture was heated at 50° C. for 24 hours to complete the addition and then fractionally distilled. This resulted in 322 g, i.e., 82%, 7-octenyl trichlorosilane and 24 g, i.e., 12%, 1,8-bis-trichlorosilyl octane.
