Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The article mentions the following:
A novel mol. gyrotop with a furan-2,5-diyl was synthesized. The furan-diyl rotor showed rotation inside the cage in a solution However, no furan-rotor dynamics was observed in a crystalline state, while a corresponding thiophene-diyl derivative showed rotation in the same condition. The lack of dynamics in the furan derivative resulted from the deformed structure of the cage caused by the small intersecting angle between two Si-C(aromatic) bonds. The experimental process involved the reaction of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium)
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.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
