- Alkenyl chlorosilanes such as vinylchlorosilane and allylchlorosilane have been widely employed as
coupling agents, which when incorporated at modest levels, enhance many of the physical properties of
polymer composites, in organic-inorganic hybrid materials industry. As a conventional method,
synthesizing alkenylchlorosilanes can be prepared by reaction of metallic silicon with alkenylchloride,
HCl in the presence of catalyst or reactions of a hydrosilylation with acetylene or butadiene derivatives of
the presence of transition metal (specially expensive Pt, Pd). We have studied synthesis of
alkenylchlorosilane by simple thermal dehydrochlorinative Si-C coupling reaction of hydrosilane with
alkenyl chloride at temperature 400 to 650℃ with out a catalyst. The yields of akenylchlorosilane depend
on the reaction temperature, feeding rate, mixing ratio of reactants and reactor type. In this presentation,
we will talk about these synthetic reaction and results in detail.
