Abstract

The long-lived transient complexes (2,3,9,10-tetramethyl-1,4,8,11-tetraazacyclo-tetradeca-1,3,8, 10-tetraene)(H₂O)Co^III-OOR²⁺, [(tim)(H₂O)Co^III-O₂R]²⁺ (R = CH₂OH, CH₂CN, CCl₃) were prepared from the reaction of [Co^II(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 [Co^III(tim)(H₂O)₂]³⁺ and formaldehyde. The results point out that the CH₃O₂^.radicals rapidly oxidize MOOR peroxides.
