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](ClO₄)₂ and O₂ under mild conditions, which are found to be more efficient than that already reported.
