Oxidation of water by a nonhaem diiron(IV) complex via proton-coupled electron transfer.

A high-potential nonhaem ( mu -oxo)diiron(iv) complex was found to oxidize water to a hydroxyl radical viaPCET, instead of forming an O-O bond. The rate-determining step requires a second water molecule, proposed to act as a base to promote proton transfer. This work shows that additional factors be... Full description
