Abstract

The long-lived transient complexes (2,3,9,10-tetramethyl-1,4,8,11-tetraazacyclo-tetradeca-1,3,8, 10-tetraene)(H2O)CoIII-OOR2+, [(tim)(H2O)CoIII-O2R]2+ (R = CH2OH, CH2CN, CCl3) were prepared from the reaction of [CoII(tim)(H2O)2]2+ with the corresponding peroxyl radicals, applying radiation chemistry techniques. The resultant transient complexes, which are relatively stable (lifetime of days), were subsequently treated with methylperoxyl (CH3O2.) radicals to form [CoIII(tim)(H2O)2]3+ and formaldehyde. The results point out that the CH3O2.radicals rapidly oxidize MOOR peroxides.
