  Activation of Alkynols by Half-Sandwich Ruthenium Complexes:  Isolation of Hydroxyalkynyl(hydrido) and Hydroxyvinylidene Derivatives

  摘要：

  The complex [Cp*RuCl(PEt3)(2)] (Cp* = C5Me5) reacts with 2-propyn-l-ol derivatives, HC=CC(OH)RR' (R = R'= H; R = R' = CH3; R = CH3, R' = Ph), in MeOH in, the presence of NaBPh4 yielding the metastable 3-hydroxyalkynyl hydride complexes [Cp*Ru(H)(C=CC-(OH)RR')(PEt3)(2)][BPh4], intermediates in the formation of the corresponding 3-hydroxyvinylidene complexes, to which these compounds rearrange both in solution and in the solid state.
