A series of silylindenes has been prepared by the reaction of (1) indenylsodium and (2) indenyllithium on alkylhalosilanes. Some reactions of the silylindenes have been studied for the purpose of further clarifying the effect of structure on the chemical behavior of the carbon- silicon bond in organosilicon compounds. A number of silylindans have been prepared by hydrogenation of the corresponding silylindenes.
