New generations of Hoveyda and bis-carbene type of ruthenium-based olefin metathesis catalysts, containing cationic cyclic alkyl amino carbene (CAAC) ligands, have been synthesized. The catalysts show exceptional stability and activity in environmentally benign, protic media. Various olefin metathesis reactions of OH functionalized feedstock (e. g. RCM, ROMP CM) can be carried out at as low as 0.05 mol % catalyst loading in methanol, isopropanol, water or methanol/water solvent mixture, accomplishing the lowest applied catalyst loading reported so far in these media. The facile olefin metathesis of renewable feedstocks including phospholipids and vegetable oils in protic media has also been demonstrated.

Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Category: chlorides-buliding-blocks
