Oxidative coupling of 2 naphthol by the use of r (cat)=5% Cu 2Cl 2 or CuCl 2 amine complexes in MeOH at room temperature in open air afforded 4 (2 hydroxy 1 naphthyl) 1
2 naphthoquinone in good yields(82% ̄96%).It shows that these kinds of copper amine complexes have the zymoid function of catalytical oxidation.
