N-Aryl indoline-type aminophosphines 1a-c were obtained in good yields by a nucleophilic aromatic substitution (SNAr) reaction followed by silane reduction. Aminophosphine 1d was also prepared from 2,3- difluorobenzaldehyde (4) via dimethylhydr

The existence of 3 as a pair of stable atropisomers has been demonstrated analytically through chiral phase LC-CD investigations. Resolution of 3d was achieved by preparative chiral HPLC. Finally, the ability of the first C(aryl)-N(amine) axially chiral p
