Abstract

Procedure for the preparation of fluoroacetamides, active component in antiparasitic agents of the general formula **(See formula)** 3 c - N-C-CHF in which X stands for oxygen or sulfur; R1 signifies hydrogen or an alkyl, alkenyl, alkynyl, alkoxyalkyl, alkylthioalkyl, alkylsulfinylalkyl, alkenyloxyalkyl, alkynyloxyalkyl or alkoxycarbonylalkyl group, an (optionally substituted) group of furfuryl, or a tetrahydrofuryl) of benzyl or the group (where R6 signifies an alkyl, halogenalkyl, alkoxy, alkylthio, alkenyloxy or alkynyloxy group); R2, R3, R4 and R5 each mean hydrogen, halogen or a group of alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl or trifluoromethyl, characterized by: a) reacting a compound of the formula **(See formula)** in which R1 through R5 and X have the same meaning as before, with a derivative of fluoroacetic acid, in the presence or absence of an acid acceptor; O well b) reacting a compound of the formula **(See formula)** in which R1 through R5 and X have the same meaning as before. with an alkali metal fluoroacetate and an inorganic acid halide, in the presence or not of an acid acceptor; O well c) reacting a compound of the formula **(See formula)** in which R1 to R5 and X have the same meaning as before, with KF, KHF2 or NaF; O well d) in case R1 is other than hydrogen, react a compound of the formula **(See formula)** in which R2 through R5 and X have the same meaning as before, in the presence of an acid acceptor, with a compound of the formula Y-R1 in which R1 has the same meaning as before and Y means halogen and, in case R1 denotes alkyl, alkenyl or alkynyl, it can also mean an alkyl- or aryl-sulfonyloxy radical.
