Abstract
Enantiomers of cis- and trans-O. N-bis-(diphenylphosphino)-2-hydroxy, 3-methylamino-norbornane have been prepared from the corresponding aminoalcohols and Ph 2PCl. These compounds have been used as ligands for the Pd and Ni complexes and were tested in asymmetric Grignard cross-coupling reactions between ( E)-β-bromostyrene and 1-phenylethylmagnesium chloride. Optical yields of up to 13% were obtained.
