DOI: 10.1021/acs.organomet.8b00041
Abstract: When the coordinating isopropyl ether of the Hoveyda precatalyst is replaced by a cyclohexyl ether, it is possible to control the substituent’s conformation in either the equatorial or axial position. A stereodivergent synthesis of axial… read more here.

DOI: 10.1039/d0qm00417k
Abstract: The second-generation Hoveyda–Grubbs (HG2) catalyst, which has a small initiation to propagation rate ratio (ki/kp) in ring-opening metathesis polymerization (ROMP), was successfully used in a recently developed catalytic living ROMP. This proved that slow-initiating catalysts… read more here.
