TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The iridium xyliphos catalyst is (Ir(1,5-cyclooctadiene)-(((R)-1-((S)-2-diphenylphosphino)ferrocenyl))ethyl-di(3,5-dimethylphenyl)phosphine)Cl).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: In the method (p2), the ratio of imine to catalyst is 20000-200000, preferably 50000-150000. The hydrogenation temperature is 20-100 degrees C. The enantiomeric excess for S-isomer of amine is 20-80%. Preferred Definitions:    R1 to R3=CH3 or C2H5;    R4=CH3, C2H5 or C3H7;    R5=CH3, C2H5, C3H7, CH(CH3)2, CH2CH(CH3)2 or CH2OCH3.    ACTIVITY - Herbicide. No biological data given.    MECHANISM OF ACTION - None given.    EXAMPLE - In a 100 ml autoclave, 12.0 g (2-ethyl-6-methyl-phenyl)-(2-methoxy-1-methyl-eth-(Z)-ylidene)-amine (a1) was diluted with 30 ml acetic acid and 20 mg tetrabutyl ammonium iodide was added to it followed by 50 mg (Ir(1,5-cyclooctadiene)-(((R)-1-((S)-2-diphenylphosphino)ferrocenyl))ethyl-di(3,5-dimethylphenyl)phosphine)Cl). The autoclave containing above mixture was flushed with argon. After sealing the autoclave, it was flushed once with argon followed by twice with hydrogen. The autoclave was pressurized to 80 bar by hydrogen gas and the temperature was raised to 50 degrees C while continuous stirring. After 24 hours when the amine (a1) was found to be absent on checking on GLC, the autoclave was cooled to room temperature and depressurized. The reaction mass was filtered and to the filtrate was added 25 ml toluene. The mixture of toluene and acetic acid were distilled off at 60 degrees OC and the hydrogenated product (S)-N-(2-ethyl-6-methyl-phenyl)-N-(1-methoxymethyl)ethylamine (b1) was distilled under high vacuum. The quantity of distilled product obtained was 11.8 g of 99% purity (yield 98%). The solid catalyst was recovered from the residue on the filter after washing with 10 ml methanol and vacuum drying and reused for next 2 cycles to get amine of 99% purity and 80% enantiomeric excess of S configuration.
