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. 50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde, molecular formula is C19H15OP. In a Article，once mentioned of 50777-76-9, name: 2-(Diphenylphosphino)benzaldehyde
[RhCl(CO)2]2 reacts with o-(diphenylphosphino)benzaldehyde (PCHO) to afford a monocarbonylated rhodium(I) complex containing P-monodentate PCHO, trans-[RhCl(CO)(PCHO)2] (1) while [RhCl(COD)]2 undergoes the oxidative addition of one PCHO, with displacement of 1,5-cyclooctadiene, and coordination of the second PCHO molecule as P-(sigma-aldehyde) chelate to give [RhH(PCO)Cl(PCHO)] (2) which contains trans P-atoms. Compound 2 reacts with H2NN=CHCH=NNH2 (gdh) to give selectively a complex [RhH(PCO)(Pgdh)]+ containing a stable hemiaminal in a new tridentate ligand, Pgdh, coordinated via the imino nitrogens and the phosphorus and the atom. The reaction of Rh(COD)(gdh)Cl with PCHO gives a mixture of the hemiaminal containing compound and the hydroxyalkyl complex [Rh(PCO)(PCHOH)(gdh)]+ which contains trans P-atoms and is formed from precursors containing cis P-atoms. The transformation of the hemiaminal group in [RhH(PCO)(PNN)]+ (PNN = Pgdh or Ppvdh (pvdh, H2NN=CHC(CH3)=NNH2)) into imine to give new tridentate PaNN ligands in complexes [RhH(PCO)(PaNN)]+ has also been studied.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: 2-(Diphenylphosphino)benzaldehyde. In my other articles, you can also check out more blogs about 50777-76-9
