Iridium-Catalyzed Enantioselective Hydrogenation of Cyclic Imines

A catalytic complex made from [Ir (COD)Cl](2) [di-mu-chloro-bis(1,5-cyclooctadiene)diridium(I)] precursor and (S,S)-f-Binaphane ((R,R)-1,1'-bis{bis{(R)-4,5-dihydro-3H-dinaphtho [1,2-c:2',1'-e]-phosphepino}ferrocene) ligand effectively catalyzed the enantioseselective hydrogenation of cyclic imines with high reactivity and good enantioselectivity.
