dc.description.abstract | A method to synthesize meso-tetraphenylbenzoporphyrin-2(2),2(3)-dicarboxylic anhydride is reported. This compound reacts with alkylamines and arylamines to afford the corresponding \"phthalimides\" in moderate to excellent yields. The reaction of the title compound with benzene-1,4-diamine or with benzene-1,3-diamine yields the corresponding N,N'-(phenylene)bisphthalimides, whereas with benzene-1,2-diamine or naphthalene-1,8-diamine it affords heterocyclic-fused porphyrins. Molecular mechanics simulations elucidates the multiplicity of signals observed in the NMR spectra of the N,N'-(1,4-phenylene)bisphthalimide 11. This molecule exhibits two preferential conformations corresponding to a coplanar and an almost perpendicular arrangement of the benzoporphyrin units relative to the central benzenic ring. | pt |
