Reduction of Fe(porphyrin)Cl complexes is known to result in Cl - dissociation, subsequent electron transfer reactions, and catalytic formation of H2 in the presence of H+. On the other hand Fe(porphyrin)NO complexes undergo reversible one-electron reductions to form anionic products that can be protonated in the case of picket-fence porphyrins. The formation of coordinated HNO ligands by this route is of biochemical interest and has been achieved for a very small number of porphyrin model complexes, specifically of ruthenium. The reduction chemistry of 6-coordinate Ru analogues Ru(por)(NO)X has been previously explored by IR spectroelectrochemistry, and depending on the ligand X, apparent NO or X-ligand loss occurs but in-depth studies in the presence of proton sources have not yet appeared. We report here a systematic study of the consequences of reduction of the title compounds by CV and spectroelectrochemistry.
