Pyrazinoporphyrins: Expanding a Pyrrolic Building Block in meso-Tetraphenylporphyrin by a Nitrogen Atom

Application of a variant of our "porphyrin breaking and mending strategy" to free base and NiII complexes of meso-tetraarylporphyrin-dihydroxylation, oxidative diol cleavage and reaction of the resulting seco-chlorin bis(aldehyde) with ammonia-generates pyrazinoporphyrins. Thus, a nitrogen atom was inserted between the two former β-carbon atoms, overall formally replacing a pyrrolic building block by a pyrazine moiety. Treatment of the initially formed pyrazine hemiaminals with alcohols converts them into the corresponding hemiaminal ethers. This stabilizes the chromophores significantly, but the free-base pyrazinoporphyrins still remain sensitive toward (acid-induced) degradation reactions. Free-base pyrazinoporphyrins possess slightly redshifted porphyrin-type UV/Vis spectra, while the spectra of the pyrazinoporphyrin NiII complexes resemble more those of metallochlorins.

[2-Methylazeteochlorinato]Ni(II): A pyrrole ring-contracted chlorin analogue

The formal replacement of one of the pyrrole rings in [meso- tetraphenylporphyrinato]Ni(II) (5Ni) by an azete moiety is reported. Thus, reaction of known chlorophin monoaldehyde 7Ni (made in three steps from 5Ni) with methyl-Grignard, followed by an acid-catalyzed ring-closure reaction, generates the title compound [meso-tetraphenyl-2-methylazeteochlorinato]Ni(II) (10Ni) in a rational and scalable process in good yields. The UV-vis spectroscopic properties of this chromophore are, as expected for this chlorin analogue, red-shifted when compared to the corresponding [porphyrinato]Ni(II) (5Ni) complex. A much improved synthesis of the starting material 7Ni by Vilsmeier-Haack formylation of [meso-tetraphenylchlorophinato]Ni(II) (8Ni) is also reported.
