Abstract

Abstract : A palladium-catalyzed bay-region annulative π-extension reaction of o -halobiphenyls with o -chloropyridinecarboxylic acids was developed. A variety of azatriphenylene derivatives could be synthesized by this approach. Abstract : A palladium-catalyzed bay-region annulative π-extension reaction of o -halobiphenyls with o -chloropyridinecarboxylic acids was developed. The reaction was carried out with a 1 : 1 ratio of substrates. A variety of azatriphenylene derivatives could be synthesized by this approach. This transformation could be applied to the synthesis of ionic liquid-crystalline molecules.
