Zusammenfassung:Vacancies: Protonation of the ruthenium carbide compounds [Cl2(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.
