Iron porphyrins with simple aminophenyl substitution are synthesized and their electrochemical CO[Formula: see text] reduction properties are studied. Fe-1, bearing an amino group in the ortho position of the phenyl ring exhibits an improved catalytic turn over frequency (TOF), lower overpotential and higher selectivity, compared with para-amino-substituted iron porphyrin (Fe-2) and the control iron tetraphenylporphyrin (Fe-3). DFT calculations also support the importance of hydrogen bonds on the reactivity of Fe-1, which facilitates the formation [Fe–CO[Formula: see text]][Formula: see text] adduct by lowering 1.45 kcal mol[Formula: see text].
