A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Recommanded Product: 29841-69-8, 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 Botteghi, Carlo，once mentioned of 29841-69-8

Asymmetrische Katalysen. XLVI. Enantioselektive Hydrosilylierung von Ketonen mit 2 und optisch aktiven Stickstoff-Liganden

The synthesis and characterisation of 16 optically active nitrogen ligands, namely, pyridinethiazolidones, pyridinethiazolines, pyridinimidazolines, Schiff bases and bipyridines, are described.These ligands are used as cocatalysts together with the procatalyst 2 in the catalytic hydrosilylation of prochiral ketones with diphenylsilane.With these homogeneous in situ catalysts, optically active 1-phenylethanol is produced from acetophenone after hydrolysis of the silyl ether.The diastereomers of N-(1-phenylethyl)-2-(2-pyridinyl)-thiazolidine-4-one give opposite optical inductions.The best optical purity of 71.6percent ee is obtained with a pinanyl-substituted bipyridine.
