SULPHONYLATED DIPHENYLETHYLENE DIAMINES, SYNTHESIS METHOD THEREOF AND USE IN TRANSFER HYDROGENATION CATALYSIS Russian patent published in 2012 - IPC C07C311/16 B01J31/22 B01J31/18 C07B41/02 C07C303/38 

FIELD: chemistry.

SUBSTANCE: invention relates to a diamine of formula

, in which A is hydrogen; B is a C1-C6 alkyl group, a phenyl-C1-C6 alkyl group; or a group selected from phenyl, naphthyl, optionally substituted with a substitute selected from C1-C6 alkyl, C1-C6 alkoxy, or a halogen; X¹, X², Y¹, Y² denote hydrogen; Z is a C1-C6 alkyl group or a C1-C6 alkoxy group. The invention also relates to a method of producing a diamine of formula (I). The invention also relates to an asymmetric hydrogenation catalyst obtained from reaction a diamine of formula (I) and a compound of formula [MX₂(arene)]₂, where M is selected from Ru, Rh, Ir, Co, Ni, Fe, Pd, Pt and X is a halogen. The catalyst is used for transfer hydrogenation and the transfer hydrogenation reaction is carried out with a cyclic ketone.

EFFECT: obtaining sulphonylated diphenylethylene diamines used in transfer hydrogenation catalysis.
