Influence of the distal guanidine group on the rate and selectivity of O(2) reduction by iron porphyrin

The O(2) reduction reaction (ORR) catalysed by iron porphyrins with covalently attached pendant guanidine groups is reported. The results show a clear enhancement in the rate and selectivity for the 4e(–)/4H(+) ORR. In situ resonance Raman investigations show that the rate determining step (rds) is...
