P, O-ferrocenes of the general formula I. wherein R 1 is a radical selected from aryl, substituted or unsubstituted, where the substituents are selected from the group of the branched or straight-chain alkyl radicals, aryl radicals, halogens, amines, thioethers or carboxylic acids, wherein R 2 , R 3 , R 4 and R 5 are the same or different and are selected from aryl, branched or straight-chain alkyl, cycloalkyl, alkoxy, aryloxy, N (alkyl) 2 , N (aryl) 2 , in each case substituted or unsubstituted, or halogen, where the substituents are selected from the group of the branched or straight-chain alkyl radicals, aryl radicals, halogens, ethers, amines, thioethers or carboxylic acids, or where R 2 and R 3 and / or R 4 and R 5 form a saturated or unsaturated, branched or unbranched ring system of the general formula Ia, wherein q is 1 or 2, and R 7 and R 8 are the same or different and are selected from branched or straight-chain alkyl radicals such as CH 3 , CH 2 CH 3 , CH (CH 3 ) 2 , C (CH 3 ) 3 or cycloalkyl radicals, where n is 0 or 1. |
