摘要：

Vacancies: Protonation of the ruthenium carbide compounds [Cl 2(L)(PR3)Ru≡C:] gives the 14-electron four-coordinate ruthenium phosphonium alkylidenes [Cl2(L)Ru= CH(PR3)]+[B(X)4]- (see scheme). These compounds which already have a vacant coordination site provide direct access to the active species in olefin metathesis catalysis and thus very fast initiation.
