Porphyrazines as molecular scaffolds: Flexible syntheses of novel multimetallic complexes

The synthesis of a range of porphyrazines bearing several alternative peripheral multidenate ligands including vicinal di-(2-hydroxy-2-methylpropanamido), di-(2-methoxy-2-oxo-acetamido), di-(2-pyridine-carboxamido) and di-(2-quinolinecarboxamido) units were reported. The polydentate ligands were converted into bimetallic complexes and tetrametallic porphyrazine dimer complexes.
