Abstract
Novel ortho-(mono-substituted amino)phenylimines being intermediates to psychotropic drugs and other drugs are economically and industrially prepared by reacting anilines with nitriles in the presence of a boron trifluoride ether adduct and a halide-type Lewis acid, if necessary together with an organic base. Furthermore, the imines can be hydrolyzed with an acid to afford the corresponding ketones.
