Facile Synthesis and X-ray Structure of Alkoxy-Functionalized Dibenzo[<i>f</i><i>g,</i><i>o</i><i>p</i>]naphthacenes

Abstract

1,3-Bis(2-bromophenyl)-2,5-diphenylbenzenes are readily available by the condensation of phenylacetates with the corresponding pyrylium salts and undergo a palladium-catalyzed dehydrohalogenation to give functionalized dibenzo[fg,op]naphthacenes
