| titleOfInvention | Process for the preparation of alpha-aryl-propionic acids and their alkaline salts |
| abstract | A process is described for the preparation of alpha-aryl-propionic acids and their alkaline salts having the formula (I):n wherein Ar represents an aromatic, heteroaromatic group containing one or several rings linked together, having overall up to 20 carbon atoms, preferably chosen from amongst phenyl-, naphthyl-, diphenyl- and thienyl groups, these in turn being possibly substituted by groups inert under reaction conditions, preferably chosen from amongst: alkyl-, cycloalkyl- and aryl- groups optionally substituted, halogens, alkoxyl groups, phenoxyl groups, ketone groups, by reaction with carbon monoxide of the corresponding secondary halides of formula (II):n wherein: Ar has already been defined, while X is a halogen chosen from Cl or Br, and which process is characterized in that the reaction is conducted in an anhydrous alcohol solvent consisting of alkanols having up to 4 carbon atoms, in the presence of alkaline hydroxides, and in the further presence of a cobalt hydrocarbonyl salt, optionally supported on resins, or of one of its precursors, at a temperature comprised between 0°C and 50°C and under substantially atmospheric pressure. n The products thus obtained have a particular use in the field of pharmaceutics (analgesics, antipyretics, etc.) and as intermediates for chemical syntheses in general in the field of high-purity chemicals, and of phytodrugs. |
