Synthesis and Application of Chiral Phospholane Ligands Bearing a Sterically and Electrically Adjustable Moiety
A series of C1-symmetric phosphine-phospholane ligands, 1-(disubstituted phosphino)-2-(phospholano)benzenes (5), which are called UCAPs, with an achiral phosphino group and a chiralphospholane which can be sterically and electricallyadjustable, has been designed and synthesized. In the asymmetric hydrogenation of (Z)-N-benzoyl-1-phenylpropenamine (3), the stereorecognition abilities of the 5d−e–Rh
