Silver carbonate-Celite

The formation of o-quinones by the above oxidative methods is less reliable since the ortho quinonoid system is more susceptible to attack by electrophilic and nucleophilic species mild conditions are therefore essential. The use of the silver carbonate/Celite reagent noted above for phenol coupling reactions is particularly suitable the conditions are those described in Expt 6.129, and they have been applied to the oxidation of catechol, 4-methylcatechol, 4-t-butylcatechol, and 3,5-di-t-butylcatechol to yield the corresponding o-quinones in almost quantitative yield. [Pg.1022]
