摘要: Chiral non-racemic complexes [ML{N(SiMe2H)2}(thf)] (M = Y, La, H2L salicylaldimine ligands derived from 2,2′-diamino-6,6′-dimethylbiphenyl) are found not to be effective catalysts for the intramolecular hydroamination of aminoalkenes, but new amino/phenoxide ligand designs without reducible functional groups led long-lived and enantioselective catalysts.
