USE OF METAL COMPLEX COMPOUNDS AS CATALYSTS FOR OXIDATION USING MOLECULAR OXYGEN OR AIR.

摘要

Use, as a catalyst for oxidation reactions using molecular oxygen and/or air, of at least one metal complex compound of formula (1) wherein Me is manganese, titanium, iron, cobalt, nickel or copper, X is a coordinating or bridging radical, n and m are each independently of the other an integer having a value of from 1 to 8, p is an integer having a value of from 0 to 32, z is the charge of the metal complex, Y is a counter-ion, q = z/(charge of Y), and L is a ligand of formula (2) wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10 and R11 are each independently of the others hydrogen; unsubstituted or substituted C1-C18alkyl or aryl; cyano; halogen; nitro; -COOR12 or -S03R12 wherein R12 is in each case hydrogen, a cation or unsubstituted or substituted C1-C18alkyl or aryl; -SR13, -S02R13 or -OR13 wherein R13 is in each case hydrogen or unsubstituted or substituted C1-C18alkyl or aryl; -NR14R15; -(C1-C6alkylene)-NR14R15; -N(+)R14R15R16; -(C1-C6alkylene)-N(+)RI4R15R16; -N(R13)-(C1-C6alkylene)-NR14Rl5; -N[(C1-C6alkylene)-NR14R15]2; -N(R13)-(CI-C6alkylene)-N(+)R14R15R16; -N[(C1-C6alkylene)-N(+)R14R15R16]2; -N(Rl3)-N-Rl4R15 or -N(R13) -N"Rl4R15R16, wherein R13 is as defined above and R14, R15 and R16 are each independently of the other(s) hydrogen or unsubstituted or substituted C1-C18alkyl or aryl, or R14 and R15, together with the nitrogen atom linking them, form an unsubstituted or substituted 5-, 6- or 7-membered ring which may contain further hetero atoms.
