Abstract: | The reaction of benzoyl peroxide with p-benzoquinone in dilute solutions in chlorobenzene was investigated by isolation and identification of some of the reaction products. The reaction is complex; the identified products were phenyl benzoquinone, benzoyloxy benzoquinone, quinhydrone of p-benzoquinone, benzoic acid, and chlorobiphenyls. There was a considerable amount of tarry quinoid products of unspecific physical properties. Neither simple disubstituted quinoid products, nor mono- or di-ethers of hydroquinone were detected. A mechanism based on these findings has been suggested for the reaction. |
