<p>Alpha-arylalkanoic esters are prepared by reacting a trivalent iodine compound of the formula <CHEM> wherein Ar is an aromatic hydrocarbon and X and Y each represent a group which can be removed as an anion, with a carbonyl of the formula <CHEM> wherein Ar<1> is an aromatic hydrocarbon, R is a hydrogen atom or an alkyl group, and R<1> is a hydrogen atom or an alkyl group, in the presence of an orthocarboxylic ester having the general formula ZC(OR<2>)3, wherein R<2> is an alkyi group and Z is a hydrogen atom or an alkyl group; the reaction being carried out in the presence of at least one solvent selected from the group consisting of hydrocarbons, halogenated hydrocarbons, lower aliphatic esters, lower aliphatic ethers, lower aliphatic nitriles, lower aliphatic alcohols, lower aliphatic acids and nitroparaffins.</p> |
