Abstract
O-Aminophenyl ketone derivatives are regio-specifically prepared by reacting an aniline unsubstituted in at least one ortho position with a nitrile in the presence of boron trihalogenide to introduce a substituted iminomethyl into the ortho position of said aniline and hydrolyzing the resulting iminomethyl compound.
