Abstract

A family of ruthenium alkylidene complexes, (H ₂IMes)RuCl ₂(=CHR)(3-bromopyridine) ₂, where R = Me, Et, nPr, as well as the corresponding PCys complexes, (H ₂IMes)RuCl ₂(=CHR) (PCy ₃), have been prepared. The PCys alkylidene complexes exhibit much higher stoichiometric reactivity than does the analogous benzylidene complex, reflecting faster dissociation of PCy ₃ from the alkylidene complexes.
