General description
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.
Free radical inhibitor
Application
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.
Oxidant used in first step of greener amine synthesis from terminal olefins by Wacker oxidation followed by transfer hydrogenation of the resultant imine.
