catalyzed N,N-diarylation reaction of amides with various di(o-bromoaryl)methanes to produce diverse 9,10-dihydroacridine derivatives. The resulting 9,10-dihydroacridine derivatives were oxidized selectively under mild conditions to afford acridine, acridinone, and acridinium derivatives. The copper-catalyzed N,N-diarylation reaction coupled with oxidative aromatization reaction enabled the facile construction

A general procedure for the preparation of three N‐heterocyclic carbene stabilized, boron‐containing acenes (9‐boraanthracene, 5‐boranaphthacene, and 6‐borapentacene) is presented. The key steps involve a transmetallation reaction between BCl3 and an appropriate stannacyclic precursor, and the dehydrochlorination of the H2IMes adduct of the chloroborane product. Comparative structural, photophysical
