Abstract
Preparation of aromatic carboxyamides by palladium-catalyzed carbonylation reaction The present invention relates to a process for the preparation of aromatic carboxyamides of formula I, which can be obtained by palladium-catalyzed carbonylation reaction of aromatic chlorides of formula II, amines of formula III and carbon monoxide in the presence of a base. 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.
