Study on the synthesis and applications of N-confused porphyrin manganese, iron and cobalt complexes has become one of the hot topics of porphyrin chemistry. Compared with the coordination chemistry of porphyrin, that of N-confused porphyrin is complicated because of the peripheral nitrogen atom, the intramolecular C—H bond and NH tautomerism. N-confused porphyrin has two NH tautomers, isomer A and isomer B. Varied functions are observed in the coordination chemistry of N-confused porphyrin such as stabilization of unusual metal oxidation states and metal-carbon bond formation. N-confused porphyrins have flexible character toward the metal oxidation state. Removal of the number of hydrogen atoms from one to three will result in a monanionic, dianionic and trianionic macrocycle. The various metal oxidation states are observed in N-confused porphyrin manganese, iron and cobalt complexes. The monovalent character of N-confused porphyrin is observed in cobalt chemistry such as CoII(2-N-RNCTPP)Cl and CoII(NCTPP). The cobalt metal takes a valence of +2 since CoII(2-N-RNCTPP)Cl has a monoanionic axial ligand and N-confused porphyrin ligand. The squar-planar Co(Ⅱ) complex CoII(NCTPP) exists the cobalt-carbon bond. The divalent and trivalent characters of N-confused porphyrins are observed in manganese, iron and cobalt chemistry. In Mn(Ⅱ) and Fe(Ⅱ) complexes of N-confused porphyrin MnII(NHCTPP)Br and FeII(NHCTPP)Br, oxidation of the metal center is observed through intramolecular C—H bond activation of N-confused porphyrin ligand, which can be converted into Mn(Ⅲ) and Fe(Ⅲ) complexes Mn(NCTPP)Br and Fe(NCTPP)Br on exposure to air in solutions. {FeNO}6 with a linear Fe-NO conformation is observed in the iron chemistry of N-confused porphyrin, which is unusually stable among the porphyrin iron nitrosyl complexes. It implies that iron N-confused porphyrin complexes can be used to study NO delivery and storage. This review covers the progress on the synthesis of N-confused porphyrin manganese, iron and cobalt complexes and their applications in the field of catalytic chemistry and biological chemistry. The synthesis methods of N-confused porphyrin manganese, iron and cobalt complexes and their applications in catalytic oxidation, cyclopropanation of alkene, nitrate reductase activity and chemical nuclease activity are introduced systematically.
