Abstract
A Ru complex bearing a 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene and styrenyl ether ligand offers significantly enhanced catalytic activity, and the styrenyl ether allows for easy recovery of the Ru complex. This catalyst promotes ring-closing metathesis (RCM) and efficient formation of various trisubstituted olefins at ambient temperature. Recyclable Ru-based complexes are also disclosed.
