The invention relates to a method for producing aryl or heteroaryl amines, ethers or thioethers (III) by cross-coupling primary or secondary amities, alcohols or thioalcohols with substituted aryl or heteroaryl compounds (I) in the presence of a Brønsted base and a catalyst or a pre-catalyst containing a) a transition metal, a complex, a salt, or a compound of a transition metal from the group V, Mn, Fe, Co, Ni, Rh, Pd, Ir, Pt, and b) at least one sulfonated phosphane ligand in a solvent or a solvent mixture corresponding to Scheme 1 wherein Hal represents fluorine, chlorine, bromine, iodine, alkoxy, trifluoromethane sulfonate, nonafluorotrimethyl-methane sulfonate, methane sulfonate, 4-nitrobenzene sulfonate, benzene sulfonate, 2-naphthalene sulfonate, 3-nitrobenzene sulfonate, 4-nitrobenzene sulfonate, 4-chlorobenzene sulfonate, 2,4,6-triisopropylbenzene sulfonate or any other sulfonate, and X represents O, S or NR″. The invention also relates to novel phosphane ligands.
