title: An efficient catalytic oxidation of p-Alkoxypenols to p-quinones using tetrabutylammonium bromide and oxone.
abstract: A catalytic oxidation of p-alkoxyphenols was developed using tetrabutylammonium bromide (TBAB) and Oxone(®). The reaction of p-alkoxyphenol (1) with a catalytic amount of TBAB in the presence of Oxone(®) as a co-oxidant in acetonitrile-water (2 : 1) gave the corresponding p-quinone (2) in excellent yield without special treatment.
