Tris(trimethylsilyl)silane is an effective reducing agent for organic halides, selenides, xanthates, and isocyanides, as well as an effective hydrosilylating agent for dialkyl ketones and alkenes.The silane functions as a mediator in the formation of intermolecular carbon-carbon bonds via radicals and allows a variety of organic substrates to be used as alkyl radical precursors.Absolute rate constants for the reaction of (Me3Si)3Si* radicals with a variety of organic compounds have been measured in solution by laser flash photolysis.At 294 K rate constants are >5 x 107 M-1 s-1 for C=C double bonds that are activated by neighboring ?-electron systems or by electron-withdrawing groups.For other substrates, reactivities decreased in the order xanthate > selenide > isocyanide > nitro > sulfide.
