apply	HOVEYDA-GRUBBS catalyst, which is a bright green crystalline solid with mp 178~181 ℃. HOVEYDA-GRUBBS catalyst is an olefin metathesis catalyst. ruthenium metathesis catalyst technology has made it possible to develop several research platforms, including: ring-opening metathesis polymerization (ROMP), ring-opening cross metathesis (ROCM), Cross metathesis (CM), closed-loop metathesis (RCM).
preparation	add C591(0.250g,0.423mmol), P426(0.216g,0.507mmol) and 10% toluene/heptane (v/v)(10mL) to a 40mL scintillation vial equipped with a magnetic stirring rod. The resulting reaction was heated to 90°C for 5 hours. The resulting precipitate was separated by filtration, washed with hexane (2 × 10mL), then with methanol (2 × 10mL), and then dried in vacuum to give C627, which is a green solid, I .e., a HOVEYDA-GRUBBS catalyst (0.146g,55.0% yield). The NMR data correspond to those reported in the literature.
