Dichlorosilane chlorination in the presence of propylene as an inhibitor at low pressures and 293 K

The strong inhibiting effect of C₃H₆ on the self-ignition of dichlorosilane–chlorine mixtures points to silylenes as chain carriers of the reaction. A critical concentration of chemically inert SF₆ (> 45%) drastically improves the inhibiting action of C₃H₆ indicating the occurrence of energy branching.
