    摘要: The present invention relates to a process for the preparation of optically active 2--halopropionic acids, in which the corresponding optically active alkyl 2--halopropionates are caused to react with a carboxylic acid at elevated temperature in a transacylation reaction with the formation of the optically active 2--halopropionic acid and the alkyl carboxylate, and the optically active 2--halopropionic acid obtained is separated from the reaction mixture. The optically active products produced are important intermediates for the preparation of plant protectants and pharmaceuticals.
