Iron Oligopyridine Complexes as Efficient Catalysts for Practical Oxidation of Arenes, Alkanes, Tertiary Amines and N-Acyl Cyclic Amines with Oxone. — A cationic Fe—quinquepyridine complex is successfully applied to the Oxone-mediated epoxidation of alkenes, e.g. (I), (III) and (VI), the oxidation of arenes to quinones[cf. (VIII), (X)], the demethylation of tertiary N-methylamines (XX), the oxidative ring opening of cyclic N-acylamines [cf. (XXVI)] as well as to the α-cyanation of amines [cf. (XXa), (XXIV)]. The loss of iron in the complex can be compensated by addition of Fe(ClO4)2. Use of SBA-15-immobilized terpyridine as ligand allows for easy recov-ery of the ligand, although the loss of iron is still observed. — (LIU, P.; LIU, Y.; WONG, E.
