Abstract

1336323 Oxadiazoles and thiadiazoles AGRIPAT SA 19 April 1971 [19 March 1970] 24649/71 Heading C2C [Also in Division A5] Compounds of formula wherein R 1 is an α-halo-C 1-6 -alkyl radical, containing 1 to 3 halogen atoms attached to the α-carbon atom, each of R 2 and R 3 is hydrogen or a C 1-6 alkyl radical, R 4 is a C 1-6 alkyl radical optionally substituted by a cyano or C 1-4 - alkoxy group, or is a C 3-10 cycloalkyl, (C 1-6 - alkyl)-C 3-10 -cycloalkyl, alkenyl, haloalkenyl or alkynyl group and X is oxygen or sulphur, are prepared by (a) reaction of a 3-R 1 -5-aminooxadiazole or thiadiazole with a halocarbonic or halothiocarbonic ester or with phosgene to give a carbamate or thiocarbamate ester or carbamic acid halide and reacting this with an amine, or (b) reaction of a 3-R 1 -5-amino-oxadiazole or thiadiazole with an isocyanate or an N-substituted carbamic acid halide. The products are herbicides. 3 - R 1 - 5 - Amino - oxadiazoles and thiadiazoles are prepared by (a) reaction of a trihaloacetamidoxime, with cyanogen bromide, (b) reaction of a 5-trichloromethyl-compound with ammonia or (c) conversion of a 3-trihalomethyl compound to a 3-dihalomethyl compound by catalytic hydrogenation. 3 - Trifluoromethyl - 5 - trichloromethyl - 1,2,4- oxadiazole is prepared by reaction of 2,2,2-trifluoro-acetamidoxime with trichloroacetic anhydride.
