Facile synthesis of unsubstituted beta,beta'-linked diformyldipyrromethanes.
Unsubstituted beta,beta'-linked diformyldipyrromethanes are promising precursors for the synthesis of novel poly dipyrromethene ligands and N-confused porphyrins. A strategy has been developed to selectively synthesize unsubstituted beta,beta'-linked diformyldipyrromethanes in moderate yields starting from 2-formylpyrrole.
