A novel centrosymmetric porphyrazine (Pz) 1 decorated with pyrazino-dibenzo[ b,f ]azepine units have been prepared via Linstead macrocyclization re action of a dinitrile precursor. Accordingly, the peripheral azepine nitrogen offers a chemical h andle for subsequent functionalizations. Characterization of the metal complexes (MPzs = Metal Porphyrazines) of 1 was accomplished and good catalytic performances were achieved in th e Cu(II)- and Co(II)- catalyzed cyclopropanation with ethyl diazoacetate as a test reaction.
