A process for the preparation of aromatic or hetero-aromatic carboxylated compounds involves the carbonylation reaction of a certain defined aromatic halogenated substrate, conducted in an alcoholic or hydro-alcoholic medium, in the presence of a basic acidity acceptor, and of a catalyst system formed of a cobalt hydrocarbonyl salt or a precursor thereof and of a certain defined halide, at a temperature from 20°C to 80°C, under substantially atmospheric pressure. n The products thus obtained may find application in the preparation of alkydic resins, of dyestuffs and pigments, and in general as intermediates in the synthesis of chemical products. |
