A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2.

Synthesis of pincer ruthenium RuCl(CNN)(PP) catalysts from [RuCl(mu-Cl)(eta6-p-cymene)]2
The cationic [RuCl(eta6-p-cymene)(HCNNa)]Cl (1a) (HCNNa = 1-(6-arylpyridin-2-yl)methanamine) and the neutral RuCl 2(eta6-p-cymene)(HCNNb) (1b) (HCNN b = 2-aminomethylbenzo[h]quinoline) complexes have been obtained by reaction of the precursor [RuCl(mu-Cl)(eta6-p-cymene)] 2 with the corresponding nitrogen ligand (HCNNa and HCNNb) in THF. Complex 1a reacts cleanly with monodentate (P = PPh3) and bidentate phosphines (PP = dppb, dppf) in ethanol in the presence of NEt3, affording the pincer catalysts RuCl(CNN a)(PPh3)2 (2) and RuCl(CNNa)(PP) (PP = dppb 3, dppf 4). Similarly, the benzo[h]quinoline pincer derivative RuCl(CNNb)(dppb) (5) is obtained from 1b and dppb. Complex 3 has also been prepared in a one-pot reaction from [RuCl(mu-Cl)(eta6-p- cymene)]2, HCNNa, and dppb in ethanol. Similarly, the chiral complex RuCl(CNNa)((R,S)-Josiphos) was isolated as a single stereoisomer by treatment of [RuCl(mu-Cl)(eta6-p-cymene)] 2 with HCNNa and (R,S)-Josiphos in 1-butanol. Reaction of 1a and 1b with dppb affords cymene diphosphine species by displacement of the HCCN ligand.
