New routes toward selective synthesis of both mono- and diaryl maleimides have been innovated. The mere requirement to this end is through the increase of temperature. The method works effectively for maleic anhydride and maleic acid as well. Also, the first expedient synthesis of 2-arylnaphthoquinones via the reaction of naphthoquinone with arenesulfonyl chlorides is revealed.
