摘要: Abstract α-Methoxyvinylmetal(II) complexes of the type trans -C 6 Cl 5 M(PPhMe 2 ) C(OMe)CH (abbr. [M]C(OMe)CH , where M = Ni, Pd, Pt) were prepared by reaction [M]Cl and LiC(OMe)=CH treated with perchloric acid to give cationic methyl(methoxy)carbene complexes, [M] + C(OMe)Me, ClO 4 − . Ethynylmetal(II) [M]CCH, [M]Cl, silver perchlorate HCCH in presence triethylamine, methanol either (M or [Pd] OH The relative Br∅nsted acidity C(OMe)Me was found be order Ni Pt. From IR, 1 H NMR 13 C spectral investigations, explained terms largest σ-bonding polarity for MC bond back π-donor ability Pt C(OMe)Me.
