A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, category: catalyst-ligand, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 29841-69-8, Name is (1S,2S)-(-)-1,2-Diphenylethylenediamine, molecular formula is C14H16N2. In a Patent, authors is ，once mentioned of 29841-69-8
The invention discloses a Salan ligand, metal – Salan complex and the preparation of chiralalpha- Hydroxy -beta- Keto acid ester compound. Specifically (1S, 2S) – 1, 2 – Diphenyl ethylene diamine-derived Salan ligand is chiral source, with the metal ion coordination for preparing metal – Salan complex, the resulting metal – Salan complex with the substrate, the oxidizing agent in organic solvent, to obtain the chiralalpha- Hydroxy -betaKeto ester -, the highest yield of 99%, the highest enantiomeric excess value of 99%, is now the highest enantioselectivity. The invention mild reaction conditions, less catalyst levels, the operation is simple, enantiomeric excess value is high, it has very good application prospect. (by machine translation)
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. category: catalyst-ligand
