Etude de la photoréactivité de la méthoxy-p-quinone et de phényl-p-benzoquinones en solution

Abstract : The study of the photoreactivity of methoxy-p-quinone/methoxyhydroquinone couple in solution had led to a better understanding of his role in the photodegradation of high-yields pulps. The mechanism of the photocyclization of some phenyl-p-benzoquinones and an analogue, the 4,4'-dimethoxybiphényle-2,5,2',5'-bisquinone obtanied by the coupling reaction between methoxy-p-quinone and methoxyhydroquinone, have been determined by steady-state and time-resolved photolysis.
