资源简介：
The synthesis of the digermyl and
germylsilyl hydronium borates 7[B(C6F5)4] and 8[B(C6F5)4] is reported. Spectroscopic (IR, NMR) and structural
data supported by the results of density functional calculations indicate
in both cases a symmetric or almost symmetric E–H–E′
three-center–two-electron linkage (7, E = E′
= Ge; 8, E = Si, E′ = Ge). The [B(C6F5)4]− and the [HCB11H5Br6]− salts of both cations
are active in catalytic hydrodefluorination reactions of alkyl and
benzyl fluorides. No significant effect of the element atom E on the
determined turnover numbers was found.
