ABSTRACT OF THE DISCLOSURE 2-Methylene-3-substituted-4, 5-bis-trifluoromethylimino-thiazolidines of the formula Image in which; R1 represents an alkyl, alkenyl or alkynyl radical which can be substituted by cyano or an alkoxy or alkylmercapto group with in either case up to 3 carbon atoms, or represents cycloalkyl which is optionally substituted by alkyl with 1 to 3 carbon atoms, or represents aryl or aralkyl optionally substituted by halogen cyano, nitro or by alkyl, alkoxy or alkylmercapto with in each case up to 3 carbon atoms, or represents an amino group -NR4R5, wherein R4 and R5 each independently represents alkyl or, together with the connecting nitrogen atom and optionally one or more further hetero-atoms selected from oxygen, sulphur and nitrogen, form a heterocyclic ring with 5 to 7 ring atoms, R2 represents hydrogen, cyano, alkoxycarbonyl or acyl, and R3 represents cyano or alkoxycarbonyl optionally substituted by an alkoxy or alkylmercapto group with up to 3 carbon atoms, or represents acyl or alkysulphonyl, or represents arylsulphnoyl optionally substituted by alkyl with up to 3 carbon atoms and/or by nitro and/or by halogen or represents an amide or thioamide group comprising the radical CO-NR6R7 or CS-NR6R7 in which R6 represents hydrogen or alkyl, and R7 represents alkyl, cycloalkyl or phenyl, which phenyl can be substituted by halogen or nitro or by alkyl, alkoxy or alkylmercapto with in each case up to 4 carbon atoms, or R2 and R3, together with the connecting carbon atom, represents an .alpha.-cycloalkanone ring system with 5 to 7 carbon atoms, which can be optionally substituted by alkyl with up to 3 carbon atoms, R2 represents hydrogen, cyano, alkoxycarbonyl or acyl, and R3 represents cyano or alkoxycar- bonyl optionally substituted by an alkoxy or alkylmercapto group with up to 3 carbon atoms, or represents acyl or alkylsulphonyl, or represents arylsulphonyl optionally substituted by alkyl with up to 3 carbon atoms and/or by nitro and/or by halogen, or represents an amide or thioamide group comprising the radical CO-NR6R7 or CS-NR R7.
