Ruthenium indenylidene "1st generation" olefin metathesis catalysts containing triisopropyl phosphite

The authors gratefully acknowledge the Royal Society (University Research Fellowship to CSJC) and the EC (CP-FP 211468-2 EUMET) for funding.The reaction of triisopropyl phosphite with phosphine-based indenylidene pre-catalysts affords “1st generation” cis-complexes. These have been used in olefin metathesis reactions. The cis-Ru species exhibit noticeable differences with the trans-Ru parent complexes in terms of structure, thermal stability and reactivity. Experimental data underline the importance of synergistic effects between phosphites and L-type ligands.Publisher PDFPeer reviewe
