reaction of bromaminic acid (1) with aniline derivatives 2a-z in phosphate buffer. Good to excellent isolated yields were obtained within only 2-20 min at 80-120 degrees C and 40-100 W. The new procedure provides the first generalaccess to anilinoanthraquinones, furnishing a number of previously inaccessible compounds. It is superior to classical methods in all aspects, including yields, reaction time
