Benzoyl derivatives of the formula I where the variables have the following meanings:

3-heterocyclyl-substituted benzoyl derivatives

The invention relates to a process for preparing semicarbazone compounds of the formula I, where Rand Rare each independently hydrogen, halogen, CN, C-C-alkyl, C-C-alkoxy, C-C-haloalkyl or C-C-haloalkoxy, and Ris C-C-alkoxy, C-C-haloalkyl or C-C-haloalkoxy, by reacting a hydrazone compound of the general formula II, where R is C-C-alkoxy, amino, C-C-alkylamino or di(C-C-alkyl)amino, and R, Rare each as defined above, with an aniline compound of the general formula III where Ris as defined above. 

Method for producing semicarbazones

A process for preparing substituted biphenyls in which in the presence of a base and of a palladium catalyst selected from the group of: a) palladium-triarylphosphine or -trialkylphosphine complex with palladium in the zero oxidation state, b) salt of palladium in the presence of triarylphospine or trialkylphosphine as a complex ligand or c) metallic palladium applied to support if appropriate,in the presence of triarylphosphine or trialkylphosphine, in a solvent, with a diphenylborinic acid (III)
