A process for the preparation of 2,2-diorgano-3-arylpropionic acids is disclosed by the carbonylation of corresponding 2,2-diorgano-1-aryl ethanol in the presence of a Lewis acid catalyst. Furthermore, a process for the production of 2,2-diorgano-3-arylpropionic esters is disclosed by reacting a corresponding 2,2-diorgano-1-aryl ethanol with carbon monoxide and an alcohol in the presence of a Lewis acid catalyst.
