Summary:This invention relates to an improved process for the preparation of 2-aryl propionic acids. Particularly this invention relates to an improved,process for conversion of aryl alkyl compound such as aryl alkyl alcohols and aryl alkyl halides having the general formula I The present invention provides an improved process for the preparation of 2-aryl propionic acid which by subjecting an aryl compound selected from an aryl alcohol or aryl halide or an aryl olefin to carbonylation in the presence of a halide source, a protonic acid, water and a heterogeneous metal and a phosphine ligand as a catalyst in an organic solvent.
