    Abstract: PCT No. PCT/EP96/00012 Sec. 371 Date Jan. 7, 1997 Sec. 102(e) Date Jan. 7, 1997 PCT Filed Jan. 4, 1996 PCT Pub. No. WO96/22272 PCT Pub. Date Jul. 25, 1996The 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.
