PROCESS FOR THE PREPARATION OF AROMATIC OR HETEROAROMATIC CARBOXYLATED COMPOUNDS

摘要

A process for the preparation of aromatic or heteroaromatic 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 DEG C to 80 DEG C, under substantially atmospheric pressure. 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.
