    Abstract: The invention relates to a method for producing substituted biphenyls of formula (I), wherein R1 = nitro or amino, R2 = cyano, halide, C1-C4 alkyl halide, C1-C4 alkoxy halide or C1-C4 alkylthio halide, n = 0 to 3 and R3 = hydrogen, cyano or halide, characterized by reacting a halobenzene of formula (I1), wherein HaI represents chlorine or bromine, with a phenyl boronic acid (IVa) of a diphenyl borinic acid (IVb) or a mixture of (IVa) and (IVb) in a solvent or diluent in the presence of a base and of a palladium catalyst which consists of palladium and a bidentate phosphorus ligand of formula (III), wherein Ar represents optionally substituted phenyl and R4 and R5 represent C1-C8 alkyl or C3-C6 cycloalkyl each or together form a two- to seven-membered bridge which can optionally carry a C1-C6 alkyl substituent.

    Abstract: Method for manufacturing aryl carboxamides of the formula (I), with Ar = singly to triply substituted phenyl , pyridyl or pyrazolyl rings, wherein the substituents are selected from halogen, C1-C4 alkyl and C1-C4 halogen alkyl; M = thienyl or phenyl, which can contain a halogen substituent; Q = direct bond, cyclopropylene, annulated bicyclo [2.2.1]heptane or bicyclo[2.2.1]heptene ring; R1 = hydrogen, halogen, C1-C6 alkyl, C1-C4 alkoxy, C1-C4 halogen alkoxy, singly to triply substituted phenyl, wherein the substituents are selected from halogen and trifluoromethylthio, or cyclopropyl; through reaction of an acid chloride of the formula (II) with an aryl amine (III) in a suitable non-aqueous solvent, wherein in the absence of an auxiliary base a) the acid chloride (II) is added, b) a pressure of 0 to 700 mbar is established, c) the aryl amine (III) is added in approximately stoichiometric amounts and d) the valuable product is isolated.
