Benzoyl halides reacted with aminothiadiazoles to yield amides I [R = 2- or 3-furyl, 2- or 3-thienyl, 2-benzofuryl or-benzothienyl, 2-indenyl, or 1- or 2-naphthyl group, 3- or 5-isoxazolyl, 2-thiazolyl, Ph, biphenylyl, halo-, acetamido, alkoxy-, (trifluoromethyl)-, methyl-, hydroxy-, (halophenyl)-, nitro-, amino-, or cyanophenyl; R1 and R2 are independently H, Cl, F, Br, Me, MeO , which exhibited insecticidal activity. Thus, 2,6-Cl2C6H3COCl was slowly added to a mixt. of 2-amino-5-(4-chlorophenyl)-1,3,4-thiadiazole and 50% NaOH and the mixt. stirred >=1 h to give I.
