  The trimethylsilyl substituent effect on the reactivity of silanes. Structural correlations between silyl radicals and their parent silanes

  摘要：

  Good linear correlations exist both between the bond dissociation energy of an Si-H bond and the corresponding SiH stretching frequency and between the Si-29 hyperfine splitting of a silicon-centered radical and J(Si-29-H) for the corresponding silane, when the successive substitution at the Si-H function takes place inside a family, i.e., (Me3Si)3-nSi(H)Men, n = 0-3. Explanations for these phenomena are advanced. Such structural correlations allow the characterization of (Me3Si)2Si(H)Me as a radical-based reducing agent with low hydrogen-donating abilities. Rate constants for the reaction of primary alkyl radicals with (Me3Si)2Si(H)Me have been measured over a range of temperatures by using competing unimolecular radical reactions as timing devices. The radical trapping abilities of this silane and other common radical-based reducing agents are compared.

The unsolvated lithiosilanes exist as the aggregated oligomers in non-polar solvents, whereas those solvated by THF or Et2O exist as monomers. Synthesis and detailed spectroscopic studies of the lithiosilanes with Si–Si bonds are reported.

  The reaction of various organosilicon hydrides including hydropolysilanes with methyl diazoacetate in the preence of copper catalyst gave α-silyl- and polysilyl- esters in 44 – 90% yields. The relative reactivities of a series of m- and p-substituted phenyldimethylsilane towards the active species generatedfrom the diazoacetate correlate well with the Hammett σ constants for the ring substituents,
