Novel η^3- Vinylcarbene Complexes Derived from Ruthenium-Based Olefin Metathesis Catalysts
Abstract
Electron-rich, disubstituted alkynes react with (H_2IMes)(PCy_3)(Cl)_2Ru═CHPh (1; H_2IMes = 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene) to form phosphine-free η^3-vinylcarbene complexes. An X-ray diffraction study on (H_2IMes)(Cl)_2Ru[η^3-(CHPh)(CPh)(CPh)] (2) confirms the unusual structure. These complexes are relevant to the mechanisms of olefin metathesis and alkyne polymerization.
