The tetrasubstituted prochiral amido-alkenes (1a, b), (2a, b), and (3b) have been homogeneously hydrogenated under very mild conditions by iridium complexes of the type [Ir(cod)(bzn)(L)][ClO4](cod = cyclo-octa-1,5-diene, bzn = benzonitrile, L = tricyclohexylphosphine or neomenthyldiphenylphosphine).
四取代的前手性酰胺基烯烃(1a,b),(2a,b)和(3b)在非常温和的条件下已通过[Ir(cod)(bzn)(L)] [ClO 4 ](鳕鱼=环辛-1,5-二烯,bzn =苄腈,L =三环己基膦或新薄荷基二苯基膦)。
