CPET reactions with acid/base sites distant from the metal center. Estimated metal-to-basic atom distances are given in the boxes at right. (A) Transfer of 1e−/1H+ from RuII(acac)2(py-imH) to TEMPO. (B) Transfer of 1e−/1H+ from TEMPOH to Ru-pyCO2− (n = 0) and RupyPhCO2− (n = 1) yields the reduced RuII/carboxylic acid complex. (C) Transfer of 1e−/1H+ from TEMPOH to iron porphyrin complexes with carboxylate oxygen atoms distant from the iron center.
