In 2022,Buchowicz, Wlodzimierz; Gunka, Piotr A.; Buchalski, Piotr; Piszcz, Michal; Bus, Sylwia; Mrozowicz, Michal; Mazur, Maria; Wasilewski, Rafal published an article in Organometallics. The title of the article was 《E/Z Switchable Ring-Closing Metathesis in 1,1′-Bis(but-3-enyl)ferrocenes: Synthesis and Characterization of Axially Chiral ansa[6]-Ferrocenes》.Computed Properties of C43H72Cl2P2Ru The author mentioned the following in the article:
Ansa[6]-ferrocenes were obtained through the Ru-catalyzed ring-closing olefin metathesis in 1,1′-bis(but-3-enyl)ferrocenes. The stereoselectivity of this reaction depended on the structure of substrates, i.e., mixtures of (E) and (Z) isomers were obtained for alkyl-substituted 3a-3d while (Z)-isomers only for aryl-substituted 3e and 3f. The ansa[6]-ferrocenes are axially chiral in the solid state according to single-crystal x-ray anal. In the case of Me-substituted derivative 4a, spontaneous resolution of the racemate was observed during crystallization The solution properties of (E) and (Z) isomers are remarkably different; the latter displays inequivalence of the two formally identical parts of the mol. at low temperatureBenzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Computed Properties of C43H72Cl2P2Ru) was used in this study.
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.Computed Properties of C43H72Cl2P2Ru
