Alkylation and reduction of porphyrins and N-substituted porphyrins: New routes to chlorins and phlorins

On reaction with organolithium compounds, N-substituted metalloporphyrins gave mixtures of mono-β-alkylated chlorins and hydroxychlorins, whereas free-base porphyrins give meso- + β- mono- and dialkylated products. Reduction of N-substituted porphyrins with tosylhydrazine or sodium tetrahydroborate opened new routes to stable phlorins.
Synthesis of N,N'-Phenyleneporphyrins. Models for Cytochrome P-450-1-Aminobenzotriazole Inactivation Products

N,N'-Phenyleneporphyrins were prepared either by oxidative cyclisation of cobalt(II)-N-phenylporphyrins or by direct interaction of a cobalt(III)-porphyrin and 1-aminobenzotriazole in the presence of dioxygen.
Acid-catalysed Intramolecular Cobalt to Nitrogen Aryl Migration and Intramolecular Reverse Reaction in Cobalt Porphyrins. Synthesis of N-Phenylporphyrins
Callot, Henry J.,Metz, Francois
, p. 947 - 948 (2007/10/02)
On acid treatment phenylcobalt(III)porphyrins yielded N-phenylporphyrin bases, while the reverse reaction was performed upon metallation by cobalt(II) and reduction; double labelling experiments showed that both migrations are intramolecular.
