Abstract

A new family of chiral diazaphospholidines is readily accessibleby phosphorylating commercially available (S)-1,1′-binaphthyl-2,2′-diamine.NMR spectroscopy, mass spectrometry and X-ray crystallographic analysisreveal their unique structures. In preliminary studies these novelmonodentate P-ligands were tested in Rh-catalyzed hydrogenationand hydroformylation (31% ee) reactions. The modular natureof the ligands allows for further structural diversity.
