Patent ID: 8338600

Claim:
Copper-(II)-oxygen adduct complexes of the general formula wherein BAr 4 stands for a tetraarylborate anion, selected from tetraphenylborate and tetrakis(3,5-trifluoromethyl)phenylborate and L represents a tripodal tetradentate ligand, wherein a) each of the four binding sites of the tripodal tetradentate ligand is a nitrogen atom, and b) three podal nitrogen-containing ligands are bound to the central nitrogen atom, and c) the tripodal tetredentate ligand L is a ligand of the general formula wherein Z 1 , Z 2 and Z 3 are selected independently of one another from each of the three podal nitrogen-containing ligands comprises, independently of one another, an aliphatic amine or a nitrogen-containing heteroaromatic compound, and d) a bridge of one to four carbon atoms is located between the central nitrogen atom and the nitrogen atom of each of the podal ligands, wherein the bridge of one to four carbon atoms exclusively comprises sp 3 -hybridized aliphatic carbon atoms, if the podal ligand is an aliphatic amine, and the aliphatic amine is bound to an alkylene group of one to four carbon atoms, according to the formula wherein Y, n, R 1 , and R 2 have the following meanings and, for each of the groups Z 1 , Z 2 and Z 3 are suitable for being selected independently of one another: Y═H or F, n=1, 2, 3, 4, and R 1 and R 2 are selected independently of one another from —H, —CH 3 , —CH 2 CH 3 , —CH 2 CH 2 CH 3 , —CH(CH 3 ) 2 , C(CH 3 ) 3 , —CF 3 , —CF 2 CF 3 , —CF 2 CF 2 CF 3 , —CF(CF 3 ) 2 , C(CF 3 ) 3 , wherein, for the case that one of the two groups R 1 or R 2 represents —C(CH 3 ) 3 or —C(CF 3 ) 3 , the other group R 1 or R 2 is selected from —H, —CH 3 and CF 3 phenyl, pentafluorophenyl, methylphenyl, dimethylphenyl, trifluoromethylphenyl, (bis-trifluoromethyl)phenyl, or if the podal ligand is a nitrogen-containing heteroaromatic compound, the bridge of one to four carbon atoms comprises exactly one sp 2 -hybridized carbon atom, wherein this sp 2 -hybridized carbon atom is part of the heterocyclic aromatic compound and is located in the 2-position to at least one nitrogen atom of the heterocyclic ring.
