Proton Coupled Electron Transfer

The excited triplet electronic state of SO2 (a3B1) reacts with water through a proton coupled electron transfer (pcet) mechanism rather than via a conventional hydrogen atom transfer (hat) process.

Computational Perspective

Hydrogen Atom Transfer (HAT) promoted by a triplet state of the bis-oxoCu2(iii) core generates a new radical rebound mechanism for the hydroxylation of methane catalyzed by the binuclear copper site of a pMMO enzyme.
