A novel carbene ruthenium complex as reusable and selective two-electron catalyst for alkene epoxidation
A new ruthenium aquo catalyst with the formula trans-[Ru(II)(CN-Me)(trpy) OH2](PF6)2 [where trpy=2,2a:6′,2″- terpyridine and CN-Me=3-methyl-1-(pyridin-2-yl)-imidazolylidene] has been prepared and thoroughly characterized by spectroscopic and electrochemical techniques. The complex has been tested in...

| Sumario: | A new ruthenium aquo catalyst with the formula trans-[Ru(II)(CN-Me)(trpy) OH2](PF6)2 [where trpy=2,2a:6′,2″- terpyridine and CN-Me=3-methyl-1-(pyridin-2-yl)-imidazolylidene] has been prepared and thoroughly characterized by spectroscopic and electrochemical techniques. The complex has been tested in epoxidation catalysis both in dichloromethane and dichloromethane:ionic liquid media, displaying excellent performances and selectivities. Reuse of the catalyst in ionic liquid:solvent media has been explored for the first time in ruthenium-mediated epoxidation catalysis and its performance is fully maintained for up to ten runs |
