report the development of a new method for the syntheses of substituted triphenylenes from the corresponding 1,2,4-trisubstituted arenes, which were themselves generated in a highlyregioselective manner according to an intermolecular alkynecyclotrimerization reaction that was catalyzed by a novel Co–TMTU complex. This highlyregioselective reaction for the formation of 1,2,4-trisubstituted arenes will
