A rational synthesis for dibenzo [fg, op] naphthacene derivatives (also named as dibenzopyrene) is described. The methodology involves the preparation of a quaterphenyl using a palladium-catalysed cross-coupling of arylboronic acids followed by chemical or photochemical cyclization. The versatility of the process is shown by the formation of various dibenzo [fg, op] naphthacene derivatives having identical or non-identical peripheral ...
