Abstract: | Two binuclear iron(III) phthalocyanine‐(μ‐oxodimer) complexes were tested in catalytic oxygenation reactions of several aromatic hydrocarbons using iodosylbenzene (PhIO)n or oligomeric iodosylbenzene sulfate [(PhIO)3SO3]n as the oxidants. Results of this study demonstrate that [(PhIO)3SO3]n is the most reactive oxygenating reagent that can be used as a safe and convenient alternative to the thermally unstable and potentially explosive iodosylbenzene. The pyridine‐containing binuclear μ‐oxobis{iron(III)‐pyridino[3,4]‐9(10),16(17),23(24)‐tri‐tert‐butyltribenzoporphyrazine} is significantly more active as compared to the traditional μ‐oxobis[iron(III)‐2,9(10),16(17),23(24)‐tetra‐tert‐butylphthalocyanine]. |
