Azuliporphyrins are intriguing porphyrin analogues that incorporate an azulene ring in place of a pyrrolic unit. This system undergoes regioselective oxidation reactions and favors the formation of stable organometallic derivatives. Reaction of meso-unsubstituted azuliporphyrins with Co2(CO)8 or CoCl2·6H2O gave 21-oxyazuliporphyrins, while Cu(OAc)2 produced the corresponding copper(ii) complexes. Treatment of an oxyazuliporphyrin with Ni(OAc)2 or Pd(OAc)2 afforded analogous nickel(ii) and… Expand

The NMR spectra for all of the metal complexes showed that they possess strong diamagnetic ring currents, although the palladium complexes gave larger downfield shifts that were slightly diminished when larger heteroatoms were present in the porphyrinoid cavity. Expand

A series of six azuliporphyrins with substituents on the seven-membered ring were prepared by two different "3 + 1" routes from 6-tert-butyl- and 6-phenylazulene, and analysis of the bond lengths suggests that a 17 atom delocalization pathway significantly contributes to the aromatic properties of this system.
