摘要

配合物[(C5Me5)RuCl(dippe)](dippe = 1,2 -二(二异丙基膦)乙烷)在NaBPh4存在下与烷基-1-炔在甲醇中反应，生成亚稳羟基-炔基衍生物[(C5Me5)Ru(H)(CCR)(dippe)][BPh4](R = CO2Me, SiMe3或Ph)，形成相应的偏乙烯配合物的中间体，这些化合物在溶液和固体中都重新排列成这些配合物。

Irreversible rearrangement of half-sandwich ruthenium hydrido-alkynyl complexes to their vinylidene isomers

The complex [(C5Me5)RuCl(dippe)](dippe = l,2-bis(diisopropylphosphino)ethane) reacts with alk-1-ynes in MeOH in the presence of NaBPh4 yielding the metastable hydrido-alkynyl derivatives [(C5Me5)Ru(H)(CCR)(dippe)][BPh4](R = CO2Me, SiMe3 or Ph), intermediates in the formation of the corresponding vinylidene complexes, to which these compounds rearrange both in solution and in the solid state.
