General description

Free radical inhibitor
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.
p-Benzoquinone (PBQ) is a cyclic conjugated diketone. Its high-resolution photoelectron spectrum has been reported. The visible and near ultraviolet spectra of PBQ have been recorded and analyzed. Its addition as coagent has been reported to enhance the crosslinking rate of polypropylene initiated by the pyrolysis of peroxides. Its impact on hemoglobin (Hb) has been investigated based on immunoblots and mass spectral analysis of a smoker′s blood.

Application

Oxidant used in first step of greener amine synthesis from terminal olefins by Wacker oxidation followed by transfer hydrogenation of the resultant imine.

Formal anti-Markovnikov hydroamination of terminal olefins
p-Benzoquinone may be used to form benzofuranone derivatives on reacting with anilides of β-aminocrotonic acids via Nenitzescu reaction.
Dienophile employed in Diels-Alder cycloadditions to form naphthoquinones, and 1,4-phenanthrenediones.
