      As the products of CH4 homolytic cleavage, H• and CH3•, are chemically soft, we hypothesize that soft, high-valent class (b) metal species are suitable intermediates towards CH4 activation. Motivated by such a hypothesis, we explored the electrocatalytic CH4 functionalization mediated by AgII metalloradical, the last class (b) transition metal whose reactivity towards CH4 is unknown. Ambient electrocatalytic CH4 functionalization with high selectivity and low activation energy was observed.
