Abstract
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)
