摘要： A novel method for producing trifluoroacetoacetic acid anilides of formula (I), wherein R has the meanings cited in the description, and trifluoroacetoacetic acid chloride is made to react with anilines of formula (III) optionally in the presence of an acid-binding agent and optionally in the presence of a diluent. The compounds of formula (I) are suitable as intermediate products in the production of uracil derivatives effectively used as herbicides. 00000
