A process for the preparation of arylamides of heteroaromatic carboxylic acids of the formula: in which each Anis nitrogen or CRn(n=1 to 5), with the proviso that at least one of the ring members is nitrogen and that two nitrogen atoms are not bonded directly to one another; R1to R5, if present, independently of one another; C1-4-alkyl or aryl, one of the substituents R1to R5being a group of the formula —OR, in which R is an optionally substituted aromatic or heteroaromatic radical; R6is hydrogen or C1-4-alkyl; and R7is an optionally substituted aromatic or heteroaromatic radical. The amides are obtained from the corresponding heteroaromatic halogen compounds, the corresponding aromatic amines and carbon monoxide in the presence of palladium diphosphine complex. Compounds of this class (Formula I) are important herbicides.
