Va. Pavlov et al., Asymmetric transfer hydrogenation of ketones catalyzed by rhodium and iridium complexes with chiral bidentate Schiff's bases, RUSS CHEM B, 50(4), 2001, pp. 734-735
Rhodium and iridium complexes of Schiff's bases derived from (1 R,2R)- and
(1S,2S).-di-aminocyclohexane catalyze asymmetric transfer hydrogenation of
alkyl aryl ketones in (PrOH)-O-i at room temperature to give chiral seconda
ry alcohols (up to 65% ee).
