The chiral M-CsDPEN [M = Ru, Rh, Ir; CsDPEN = (R,R,R)- or (S,S,S)-N-camphorsulfonyl-1,2-diphenylethylenediamine] catalysts were shown to be efficient for the asym. transfer hydrogenation (ATH) of aryl ketones by formate in neat water. Of particular note is the Ir-(R,R,R)-CsDPEN catalyst, which catalyzes the ATH of a wide range of ketones and delivers almost full conversions within a few hours at a S/C ratio of 1000 at 40° in most cases, with enantioselectivities ≤98% ee. In the experiment, the researchers used many compounds, for example, (R)-4-(1-Hydroxyethyl)benzonitrile (cas: 101219-69-6Related Products of 101219-69-6).
(R)-4-(1-Hydroxyethyl)benzonitrile (cas: 101219-69-6) belongs to nitriles. The R-C-N bond angle in and nitrile is 180° which give a nitrile functional group a linear shape. Both the carbon and the nitrogen are sp hydridized which leaves them both with two p orbitals which overlap to form the two π bond in the triple bond. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Related Products of 101219-69-6
