Patent ID: 7161005

Claim:
A method of oxidizing an oxdizable substrate which comprises bringing the oxidizable substrate into contact with a metal complex compound of formula [L n Me m X p ] z Y q (1), wherein Me is manganese, titanium, iron, cobalt, nickel or copper, X is CH 3 CN, H 2 O, F − , Cl − , Br − , HOO − , O 2 2−, O 2− , R 17 COO − , R 17 O − , LMeO − or LMeOO − wherein R 17 is hydrogen or unsubstituted or substituted C 1 –C 18 alkyl or aryl, 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 Y), and L is a ligand of formula wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 and R 11 are each independently of the others hydrogen; unsubstituted or substituted C 1 –C 18 alkyl or aryl; cyano; halogen; nitro; —OOOR 12 or —SO 3 R 12 wherein R 12 is in each case hydrogen, a cation or unsubstituted or substituted C 1 –C 18 alkyl or aryl; —SR 13 , —SO 2 R 13 or —OR 13 wherein R 13 is in each case hydrogen or unsubstituted or substituted C 1 –C 18 alkyl or aryl; —N(R 13 )—NR′ 13 R″ 13 wherein R 13 , R′ 13 and R″ 13 are as defined above for R 13 ; —NR 14 R 15 or —N⊕R 14 R 15 R 16 wherein R 14 , R 15 and R 16 are each independently of the other(s) hydrogen or unsubstituted or substituted C 1 –C 18 alkyl or aryl, or R 14 and R 15 together with the nitrogen atom bonding them form an unsubstituted or substituted 5-, 6- or 7-membered ring which may optionally contain further hetero atoms; with the proviso that R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 and R 11 are not simultaneously hydrogen, as a catalyst for the oxidation reactions.
