Abstract
It has been found that [VO(acac)2] and [Co(acac)3] increase the rate of t-BuOOH photolysis, whereas [Fe(acac)3] has the opposite effect. Redox changes of the catalytically active [VO(acac)2] were followed using the EPR technique. An EPR signal from a free radical intermediate of photochemical decomposition of t-BuOOH was recorded, and the concentration of the intermediate was monitored during the reaction.
