摘要：

Complexes of the ligand (S,S)-1-(2-diphenylphosphanyl-naphtalen-1-yl)-3-(2-isopropyl-phenyl)-4,5-diphenyl-imidazolin-2-ylidene, a representative of a new class of chiral ligands, were obtained via a short route starting from (S,S)-1,2-diphenyl-ethylen-1,2-diamine; a Rh-complex was found to promote catalytic hydrogenation of a,p unsaturated esters with up to 99% ee.
