Combined CEPT (coupled electron–proton transfer)/OAT (oxygen atom transfer) reactions were accomplished in (Bu 4 N) 2 [Mo IV O(bdtCl 2 ) 2 ] ( 1 ) and (Bu 4 N) 2 [Mo VI O 2 (bdtCl 2 ) 2 ] ( 2 ) complexes in aqueous media. The reaction mechanism of the CEPT reaction was analyzed electrochemically and the conversion of 1 to 2 was revealed to proceed by a two‐proton two‐electron oxidative process. The structural and reaction profiles provide a new model for the arsenite oxidase catalytic center. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
