Abstract
The present invention is a process for the preparation of omega-alkenylchlorosilanes. The process comprises reacting a mixture comprising an .alpha.,.OMEGA.-diene and an organohydrosilane in the presence of a supported platinum catalyst to form an .OMEGA.-alkenylchlorosilane, where the mole ratio of the .alpha.,.OMEGA.-diene to the organohydrosilane is within a range of about 6:1 to 50:1. A preferred process is run as a continuous process employing a fixed-bed of silica gel supported platinum catalyst and excess .alpha.,.OMEGA.-diene is recovered and recycled to the process.
