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.

Mono- and Di-dentate Tertiary Phosphine and Monodentate Tertiary Phosphite Derivatives of
The reactions of the butterfly cluster with a range of tertiary phosphines and diphosphines and with a large excess of trimethyl phosphite have been explored.Twenty-two derivatives of the general types (x=1 or 2), xBH2> (x=2-4), Ru4H(CO)11(L-L)BH2>, and <2> (L-L=diphosphine) have been synthesised and characterised by mass spectrometry and IR and multinuclear NMR spectroscopies.The single-crystal structures of , trans-2BH2> and *CH2Cl2 (dppe=Ph2PCH2CH2PPh2) have been determined.In the PPh3 ligand occupies a wing-tip equatorial site.In 2BH2> the two P(OMe)3 ligands are also in such sites and both the isomers in which these ligands are mutually cis or trans with respect to the cluster core are formed; the solid-state structure of the trans isomer has been confirmed.When the two phosphorus-donor atoms are provided in the form of a didentate ligand the sites of co-ordination depend upon the nature of the backbone of the ligand.In , the dppe ligand bridges a Rwing tip-Ruhinge edge and two isomers are observed in solution; the solid-state structure of one isomer has been elucidated.Use of the diphosphine ligands allows the formation of linked dicluster species, and the competition for the formation of linked and monocluster species in which the ligand behaves in either a mono- or di-dentate fashion has been investigated.In the case of dppa an additional product when the ligand is in a four-fold excess is in which both dppa ligands are pendant and co-ordinated to different wing-tip ruthenium atoms.
