Upon the two sequential one-electron reductions of the nickel(II) hangman porphyrin, intramolecular proton transfer from the pendant carboxylic acid to the meso carbon of the ligand is promoted to form the phlorin species. The first reduction is metal based, and the second reduction is ligand based; however, protonation of the ligand proceeds via a proton-coupled electron transfer reaction in which an electron is intramolecularly transferred from the nickel center to the ligand to form a formally nickel(II) phlorin.
