Abstract
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.
