A. Iwado et al., Catalytic activity of anion-exchange resins modified with metal-porphine in oxidative reactions of phenols, CHEM PHARM, 48(11), 2000, pp. 1831-1832
Anion-exchange resins modified,vith metal-porphine (M-P,) have been investi
gated to develop a solid catalyst in the oxidative reaction of phenols by O
-2 in air, Co-P-r, which is easily prepared and separable from the reaction
mixture, has been proved to accelerate the oxidative reaction of phenols s
uch as 3,5-di-tert-butyl-4-hydroxyanisole. The resulting main oxidative pro
ducts were identified to be quinones by using the GC-MS method.
