Acetanilides I (R = H, C1-5 alkyl, alkoxy; R1, R2 = H, halogen, C1-5 alkyl or alkoxy, 1-alkoxyalkyl; X = Cl, Br, I; A = azole or substituted azoles), useful as selective herbicide, were prepd. by the reaction of 2-halo-N-halomethylacetanilide (II) and monohydrogene azole (H-A) at 0≦̸C-200≦̸C. Thus, a mixt. of 16.5 2-chloro-2',6'-dimethyl-N-chloroacetanilide and 9.3wt. % 1,2,4-triazole was refluxed in 60wt.% THF for 8hr, cooled, filtrated, and condensed to give 21.0 wt.% 2-chloro-2',6'-dimethyl-N-(1,2,4-triazole-1-yl-methyl) acetanilide (m.p.115-118≦̸C).
