ABSTRACT:
Novel fluoromethylthiobenzoyl fluorides are prepared by reacting a trichloromethylthiobenzoyl chloride with hydrogen fluoride at from 10.degree. to 130.degree. C., and are useful starting materials for the preparation of crop protection agents. The process of the invention is selective in permitting the optional production of either a trifluoromethylthiobenzoyl fluoride or a difluoromonochloromethylthiobenzoyl fluoride, depending upon the temperature employed.
