The present invention relates to a process for the preparation of aromatic carboxyamides of formula I, which can be obtained by a palladium-catalyzed carbonylation reaction of aromatic chlorides of formula II, amines of formula III and carbon monoxide in the presence of 1,5,7-triazabi-cyclo[4.4.0]dec-5-ene. The invention further relates to a process for the preparation of aryl-5-trifluoromethyl-1,2,4-oxadiazoles, which are known for controlling phytopathogenic fungi.
