摘要:
IR and NMR data showed that the ionic complex Pd-2(CHdropCC(6)H(5))(2)(C5H7O2)(3)(BF3)(2)BF4 isolated in the reaction Pd(Acac)(2) + PA + 5BF(3)OEt(2) (Acac is C5H7O2, PA is phenylacetylene) is an adduct of two complexes, namely, (Acac)PdBF4 and [(PA)(2)Pd(C-3-Acac . BF3)](+)(Acac . BF3)(-) (coordinatively unsaturated). On dissolution in deuteroacetone or deuteromethanol, the [(Acac)PdF2BF2Pd(C-3 -Acac . BF3)(PA)(2)](+)(Acac . BF3)(-) adduct decomposed to Pd(Acac)(2), 2BF(3) . L(L = (CD3)(2)CO, CD3OD) and the [L(PA)(2)Pd(C-3 -Acac]+BF4- complex.
