Patent ID: 7276630

Claim:
A process for preparing compounds of the general formula (I) where R 1 to R 10 are each independently hydrogen, C 1 -C 12 -alkyl, C 1 -C 12 -alkoxy, C 4 -C 18 -aryl or C 5 -C 19 -arylalkyl, C 1 -C 12 -alkoxy, C 1 -C 12 -fluoroalkoxy, nitrile, ester, amide, ketone, aldehyde, hydroxyl, carboxyl or fluorine, comprising reacting compounds of the general formula (II), where R 6 to R 10 are each as defined above for the general formula (I) with compounds of the general formula (III) where X is chlorine, bromine or iodine and R 1 -R 5 are each as defined above for the general formula (I), wherein the reaction is effected in the presence of at least one palladium complex which bears, as ligands, at least one compound of the general formula (IV) where R 11 and R 12 are each independently C 1 -C 12 -alkyl or C 5 -C 19 -arylalkyl, R 13 and R 14 are each independently hydrogen, C 1 -C 6 -alkyl, C 1 -C 6 -dialkylamino or C 1 -C 6 -alkoxy, the R 15 radicals are each independently hydrogen, C 1 -C 12 -alkyl, C 1 -C 12 -alkoxy, C 1 -C 12 -fluoroalkyl, C 1 -C 12 -fluoroalkoxy, fluorine, C 4 -C 18 -aryl or C 5 -C 19 -arylalkyl, and the arrows indicate the possible bonding sites to the particular aryl radical, and n and m are each independently 0, 1, 2, or 3 and in the presence of mixtures of organic solvents comprising at least one solvent selected from the group consisting of optionally substituted aromatic hydrocarbons and at least one polar solvent and in the presence of at least one alkali metal- or alkaline earth metal-containing base.
