aminophosphine ligandi-Pramphos, containing a potentially stereogenic nitrogen atom, from (S)-N-isopropyl-N-methyl-α-methylbenzylamine is described; its complex with palladium(II) chloride was obtained. NMR spectroscopy revealed that the coordination of the aminophosphine with the metal resulted in stereospecific locking of the donor nitrogen atom in only one of two possible configurations.
