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. 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2.

Synthesis, chirooptical properties and catalytic activity of diene-rhodium(I) and -iridium(I) cationic complexes containing binaphthyl, C2-symmetric diamine ligands
New cationic rhodium(I) and iridium(I) complexes [M(diene)(diamine)]BF4 containing chiral C2-symmetric diamines [M = rhodium; diamine = 2,2?-diamino-1,1?-binaphthyl (BNDA), diene = cycloocta-1,5-diene (COD), 1a, bicyclo[2,2,1]hepta-2,5-diene (NBD), 1b, hexa-1,5-diene (HEX), 1c; diamine = N,N?-dimethyl-2,2?-diamino-1,1?-binaphthyl (DMBNDA), diene – COD, 1d. M = iridium; diamine = BNDA, diene = COD, 2a; diamine = DMBNDA, diene = COD, 2b] have been prepared by the reaction of [MC1(diene)]2 with AgBF4 and further treatment with the diamine. Using N,N,N? ,N?-tetramethyl-2,2?-diamino-1,1?-binaphtyl (TMBNDA), no cationic complex was obtained. With the exception of the complex 1c, complexes 1 and 2 are stable in solution under inert atmosphere. Acetonitrile removes bonded DMBNDA but not BNDA from the metal; KOH removes both the diamines but not the diene. Complexes 1a, 1b, and 2a, containing (+)(R)-BNDA, catalyze the enantioselective hydrogenation of (Z)-alpha-acetamidocinnamic acid to acetamidodihydrocinnamic acid (o.p. = 9%; room temperature; hydrogen pressure, 35 atm).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 4488-22-6. In my other articles, you can also check out more blogs about 4488-22-6
