The present invention relates to the use of metal complex compounds with terpyridine ligands as oxidation catalysts. The present invention relates also to formulations comprising such metal complex compounds, to novel metal complex compounds, and to novel ligands. The metal complex compounds are used especially tor improving the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibres and dyeings.

Use of metal complex compounds as oxidation catalysts

Use of metal complex compounds of formula[LMeX]Y&#x2003;&#x2003;(1),wherein Me is manganese, titanium, iron, cobalt, nickel or copper, wherein R, R, R, R, R, R, R, R, R, Rand Rare each independently of the others hydrogen; unsubstituted or substituted C-Calkyl or aryl; cyano; halogen; nitro; &#x2014;COORor &#x2014;SORwherein Ris in each case hydrogen, a cation or unsubstituted or substituted C-Calkyl or aryl; &#x2014;SR, &#x2014;SORor &#x2014;ORwherein Ris in each case hydrogen or unsubstituted or substituted C-Calkyl or aryl; &#x2014;N(R)&#x2014;NR'R&#x2033;wherein R, R&#x2032;and R&#x2033;are as defined above for R; &#x2014;NRRor &#x2014;NRRRwherein R, Rand Rare each independently of the other(s) hydrogen or unsubstituted or substituted C-Calkyl or aryl, or Rand Rtogether 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, R, R, R, R, R, R, R, R, Rand Rare not simultaneously hydrogen, as catalysts for oxidation reactions,and the novel metal complex compounds of formula (1) and the novel ligands of formula (2).

Use of metal complex compounds of formula[LMeX]Y,&#x2003;&#x2003;(1)wherein Me is manganese, titanium, iron, cobalt, nickel or copper, wherein R, R, R, R, R, R, R, R, R, Rand R, are each independently of the others hydrogen; unsubstituted or substituted C-Calkyl or aryl; cyano; halogen; nitro; &#x2014;COORor &#x2014;SORwherein Ris in each case hydrogen, a cation or unsubstituted or substituted C-Calkyl or aryl; &#x2014;SR, &#x2014;SORor &#x2014;ORwherein Ris in each case hydrogen or unsubstituted or substituted C-Calkyl or aryl; &#x2014;N(R)&#x2014;NR'R&#x2033;wherein R, R&#x2032;and R&#x2033;are as defined above for R; &#x2014;NRRor &#x2014;NRRRwherein R, Rand Rare each independently of the other(s) hydrogen or unsubstituted or substituted C-Calkyl or aryl, or Rand Rtogether with the nitrogen atom bonding them form an unsubstituted or substituted 5-, 6- or 7-membered ring which may optionally contain further hetero atoms;

Use of metal complex compounds of formula[LMeX]Y&#x2003;&#x2003;(1)wherein Me is manganese, titanium, iron, cobalt, nickel or copper, wherein R, R, R, R, R, R, R, R, R, Rand Rare each independently of the others hydrogen; unsubstituted or substituted C&#x2013;Calkyl or aryl; cyano; halogen; nitro; &#x2014;COORor &#x2014;SORwherein Ris in each case hydrogen, a cation or unsubstituted or substituted C&#x2013;Calkyl or aryl; &#x2014;SR, &#x2014;ORor &#x2014;ORwherein Ris in each case hydrogen or unsubstituted or substituted C&#x2013;Calkyl or aryl; &#x2014;N(R)&#x2014;NR'R&#x2033;wherein R, R&#x2032;and R&#x2033;are as defined above for R; &#x2014;NRRor &#x2014;NRRRwherein R, Rand Rare each independently of the other(s) hydrogen or unsubstituted or substituted C&#x2013;Calkyl or aryl, or Rand Rtogether with the nitrogen atom bonding them form an unsubstituted or substituted 5-, 6- or 7-membered ring which may optionally contain further hetero atoms;
