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, SDS of cas: 50777-76-9
Hydrocarbon solutions of PtPCy3(C2H4)2 (Cy = cyclohexyl) react rapidly with 8-quinolinecarboxaldehyde (1 equiv.) to yield tricyclohexylphosphine quinoline-carboxyl platinum hydride (1) and CH2CH2 (2 equiv.).Compound 1 reacts with CCl4 in hydrocarbons to give PtPCy3(NC9H6CO)Cl (2) and CHCl3.The compound PtPCy3(C2H4)2 also reacts with Ph2P(C6H4-o-CHO) and Ph2As(C6H4-o-CHO) to give PCy3PtPh2P(C6H4-o-CO)(H) (3) and PCy3PtPh2As(C6H4-o-CO)(H) (4), respectively.Compounds 1, 2, 3, and 4 were characterized by infrared and 1H NMR spectra, and the crystal structure of 3 was determined by X-ray diffraction.Crystals of 3 are monoclinic, with space group P21/n and Z = 4 with the unit cell dimensions a 9.7936(17), b 14.844(35), c 23.530(64) Angstroem, beta 91.817 (18)deg, and V 3419.09(1.36) Angstroem3.The structure is refined to final discrepancy factors of R = 0.055, and Rw = 0.064.The molecular structure of 3 is that ligating atoms are in a plane containing Pt.The position of the hydride was not located crystallographically, but the 1H NMR spectrum of 3, supports the presence of a terminal hydride that is cis to the carbonyl.The IR band of 3 at 2023 cm-1, which is assigned to nu(Pt-H), and the hydride cleavage reaction of 1 with CCl4, provide evidence for the Pt-H bond.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 50777-76-9. In my other articles, you can also check out more blogs about 50777-76-9
