Ir(III) complexes of diamine ligands for asymmetric ketone hydrogenation
摘要:
The use of a combination of IrCl3 with a series of ligands derived from the C2-symmetric diamine di-phenylethanediamine (DPEN) forms a catalyst capable of the asymmetric hydrogenation of ketones in up to 85% ee. (C) 2009 Elsevier Ltd. All rights reserved.
