An Efficient Catalytic Oxidation of p-Alkoxypenols to p-Quinones Using Tetrabutylammonium Bromide and Oxone

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 yiel...

Zusammenfassung: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.
