Abstract:
A process for oxidation, which comprises oxidizing an oxidizable substrate with a mixture of a peroxygen compound and, as oxidation catalyst, a Mn(III) or Fe(III) metal complex containing a tripodal ligand of the formula whereR1, R2, R3, R4, R1â€², R2â€², R3â€², R4â€², R1â€³, R2â€³, R3â€³ and R4â€³ are each independently hydrogen, cyano halogen, SO3M, where M is hydrogen, an alkali metal cation, an alkaline earth metal cation, ammonium or an organic ammonium cation, SO2NH2, SO2NHR5, SO2N(R5)2, OR5 or COOR5, where R5 is hydrogen or linear or branched C1-C4alkyl, nitro, linear or branched C1-C8alkyl, linear or branched fluorinated or perfluorinated C1-C8alkyl, NHR6, NR6R7, NâŠ•R6R7R10 or linear or branched C1-C8alkyl-R8, where R8 is OR5, COOR5, NH2, NHR6, NR6R7 or NâŠ•R6R7R10, where R6, R7 and R10 are indentical or different and each is linear or branched C1-C12alkyl or where R6 and R7 combine with the joining nitrogen atom to form a 5-, 6- or 7-membered ring, which may contain further heteroatoms, and where R9, R9â€² and R9â€³ are each independently hydrogen, linear or branched C1-C8alkyl or aryl.
