摘要
The six multiimidazole copper（Ⅰ） complexes are utilized to mimic tyrosinase. The main product is 3,5-di-t-butylcatechol from o-hydroxylation of the substrate 2,4-di-t-butylphenol. The highest yield of catechol is up to 82.2% and selectivity 94.8% by [Cu（Ⅰ）2（3b）（MeCN）2]（CIO4）2 and O2 under mild conditions, which are found to be more efficient than that already reported.
