Abstract

Various bisflavylium dications have been prepared in an efficient four-step manner utilizing the acid-mediated condensation between bis(arylethynylketones) and activated phenols as the key step. Of special note is that phloroglucinol-type bisflavylium salts have been obtained for the first time thanks to this procedure.
