Abstract
Organometallic complexes suitable as olefin metathesis catalysts are provided. The complexes are Group 8 transition metal carbenes bearing a cationic substituent and having the general structure (I)wherein M is a Group 8 transition metal, L1 and L2 are neutral electron donor ligands, X1 and X2 are anionic ligands, m is zero or 1, n is zero or 1, and R1, W, Y, and Z are as defined herein. Methods for synthesizing the complexes are also provided, as are methods for using the complexes as olefin metathesis catalysts.
