INTRA- AND EXTRADIOL OXYGENATIONS OF 3,5-DI-<i>TERT</i>-BUTYLCATECHOL CATALYZED BY BIPYRIDINEPYRIDINEIRON(III) COMPLEX

Abstract

Abstract Iron(III) complex coordinated by 2,2′-bipyridine and pyridine catalyzes oxygenation of 3,5-di-t-butylcatechol with molecular oxygen to give intra- and extradiol fission products as well as oxidation to give 3,5-di-t-butyl-1,2-benzoquinone. Structures and reactivities of the products have indicated that the oxygenation proceeds by the Hamilton process rather than the dioxetane process.
