ABSTRACT OF THE DISCLOSURE Process for preparing esters of alkanoic acids via rearrangement of alpha-haloketals in the presence of a Lewis acid. The reaction is preferably carried out in the presence of catalytic amounts of a Lewis acid and of a diluent at a temperature in the range from about 0° to the reflux temperature of the diluent. The esters thus obtained are useful as inter- mediate products for preparing drugs. The process involves the preparation of new alpha-haloketals.
