Chiral non-racemic complexes [MLN(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 to long-lived and enantioselective catalysts.
手性非外消旋复合物 [MLN(SiMe2H)2}(thf)] (M = Y, La, H2L = 源自 2,2′-二氨基-6,6′-二甲基联苯的水杨醛亚胺配体) 被发现对于氨基烯烃的分子内氢胺化反应并不是有效的催化剂,但没有可还原功能团的新型氨基/酚氧配体设计则导致了长效且具选择性的催化剂。
