Summary

The reaction of dialkyl(or aryl)dichlorosilanes with conjugated dienes in presence of alkali metals in a tetrahydrofuran medium leads to the formation of unsaturated sila-hydrocarbon polymers with silicon atoms in the main chain and molecular weights of 1000 or over, and also the corresponding silacyclopentenes (yields 0–10%) and divinylsilacyclopentanes (yields 10–50%). The relative amounts (yields) of these products depend both on the nature of the reactants and on the reaction conditions.
