Diporphyrinylamines: Synthesis and Electrochemistry
摘要:
The synthesis of three possible diporphyrinylamines is described. All compounds were obtained by using the Buchwald-Hartwig aromatic amination reaction. The electronic spectra of the three porphyrin dimers showed characteristic features found In highly delocalized systems. The first oxidation of these compounds took place on the connecting amine function.

A general and efficient synthesis of fused five-membered porphyrins from the readily available beta-brominated porphyrins via palladium-catalyzed intramolecular cyclization has been developed, which can be applied for various metal complexes of beta-brominated porphyrins or free base ones and generally results in good yields of the fused five-membered porphyrins.
