The mechanism of aromatic hydroxylation for 2-methyl substituted analogues of copper complexes studied previously, namely [Cusub 2}(Mesub 2}XYL-CHsub 3})]sup 2+} (4) and [Cusub 2}(XYL-CHsub 3})]sup 2+} (5) are described in detail. Manometric Osub 2} uptake experiments and labeling studies were used to unravel the reaction pathway. The NIHshift mechanism is said to be operative in a copper
