Abstract
With hydrogen peroxide as oxidant, we got a high selectivity of 2-hydroxy-1 ,4- naphthaqinone from 1- and 2-naphthol in methanol solution containing so dium hydroxide at low temperature. A series of tetraphenylporphyrin ferron chloride and its corresponding substitutes are employed as catalysts. By de termination of UV-Vis and EPR spectra in situ, a probable mechanism model w as established.
