An efficient chemoselective dominooxidative homocoupling of 2-aminoaryl ketones in the presence of 2-iodoxybenzoic acid (IBX) for the synthesis of iminoquinone has been developed. The domino reaction proceeds via three consecutive steps, such as domino ortho-hydroxylation of 2-aminoaryl ketones, oxidation of a phenol derivative to benzoquinone and dimerization through imine formation to yield iminoquinone
