摘要：
The present invention is directed to a method for producing dichlorophenylthioglycolic acid which comprises reacting monobromodichlorobenzene or trichlorobenzene with a thioglycolate in a ratio of 0.5 to 2.5 mols of the latter to 1 mol of the former in a polar solvent, and to a method for producing dichlorophenylthioglycolic acid comprising further reacting the reaction mixture obtained as above with a monohalogenoacetate.
The method of the present invention is very useful, industrially advantageous and results in a high yield.
