Dipyrromethanes are useful intermediates in the synthesis of porphyrins and their analogs. In this paper, we report the synthesis of a new bis(dipyrromethane) {(E)-1,2-bis[4-[di(1H-pyrrol-2- yl)methyl]phenyl]ethene}, from (E)-4,4'-1,2-ethenediylbis(benzaldehyde), showing a long resonance chain with improved UV spectrometric properties. This product has high potential in the synthesis of new bis(porphyrins) or other related compounds.
Keywords: Aldehydes, bis(dipyrromethanes), bis(porphyrins), dipyrromethanes, porphyrins, pyrrole.
