Synthetic Route of 12150-46-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8
The pincer complexes [MX(CNN)(PP)] (M = Ru, Os; X = Cl, OTf; HCNN = 1-(6-arylpyridin-2-yl)methanamine; PP = diphosphine) have proven to efficiently catalyze both racemization and deuteration of alcohols in the presence of a base. Chiral alcohols have been racemized at 30-50 C using 1 mol% of Ru or Os pincer complexes and 5 mol% of KOtBu in 2-propanol. Primary and secondary alcohols are efficiently deuterated at the alpha position, with respect to the OH group, using 2-propanol-d8 as solvent with Ru or Os pincer complexes and KOtBu at 30-50 C. For secondary alcohols incorporation of deuterium at the beta position has also been observed. In 2-propanol-d 8 the pincer complexes catalyze the simultaneous deuteration and racemization of (S)-1-phenylethanol, the two processes being strictly correlated. For both reactions much the same activity has been observed with the Ru and Os complexes. The pincer complexes display a superior activity with respect to the related compounds [MCl2(NN)(PP)] (NN = bidentate amine or pyridine ligand). The synthesis of the new complexes [MCl(CNN)(PP)] (M = Ru, 2, 4 and Os, 6, 7; PP = dppb, dppf) and [Ru(OTf)(CNN)(dppb)] (3) is also reported. The Royal Society of Chemistry 2011.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 12150-46-8 is helpful to your research., Synthetic Route of 12150-46-8
