Abstract A general and versatile synthetic approach to a broad series of aromatic triynes as precursors to helicene derivatives has been developed. Employing a set of simple tools, triynes comprising the (phenylethynyl) benzene, 1-(phenylethynyl) naphthalene, and 1-(1- naphthylethynyl)-naphthalene moiety have been prepared in good to excellent yields throughout the whole reaction sequence. The methodology allows constructing various ...
