Polysilahydrocarbons, such as tetrasilanes, are prepared by reaction of alkenyl organometallic compounds with alkyltrihalosilanes, followed by further reaction of the alkyltrialkenylsilane intermediates with trihalosilane and the subsequent substitution of the halogen atoms in the second intermediate by alkyl groups.

Polysilahydrocarbon lubricants

Trisilahydrocarbon synthetic lubricant base stocks are prepared by the reaction of dienes containing four to sixteen carbon atoms with dihalosilanes, followed by further reaction of the bis(alkenyl)dihalosilane intermediates with trihalosilanes or trialkylsilanes, followed by substitution of the halogen atoms in the second intermediates by organometallic compounds or by hydridometallic compounds plus olefins.
