A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Computed Properties of C14H16N2, 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 Article, authors is Fu, Ji-Ya，once mentioned of 29841-69-8
A series of secondary amine-thiourea catalysts derived from l-proline and chiral diamine were prepared and first applied to highly enantioselective amination of unmodified aldehydes with various azodicarboxylates in excellent yields (up to 99%) and enantioselectivities (up to 99% ee) within a few minutes.
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. Application In Synthesis of (1S,2S)-(-)-1,2-Diphenylethylenediamine
