P-BENZOQUINONE FOR SYNTHESIS 1 KG

Application

p-Benzoquinone can be used as:

• A free-radical inhibitor.
• A catalyst to synthesize highly site-selective N1-alkylated benzotriazoles by N1-alkylation of benzotriazoles with diazo compounds.
• A hydrogen acceptor and two electron oxidant in Pd-catalyzed Wacker oxidation of aryl olefins aldehydes.
• A redox mediator in Pd-catalyzed anaerobic electrooxidative homocoupling of aryl-boron derivatives.
