This invention is directed to certain substituted aryloxy benzotriazole compounds which are herbicidal agents. The structures of these compounds are represented by formulas I and II shown below: <IMAGE> I or <IMAGE> II wherein M is C-X, N or N+-O-; W, X, Y and Z each independently represent hydrogen, halogen, nitro, cyano, C1-C4 haloalkyl or C1-C4 haloalkoxy; n is 0, 1 or 2; R is hydrogen, C1-C4 alkyl, aryl or when taken together with R1, R and R1 may form a ring in which RR1 are represented by the structure -(CH2)m- where m is an integer of 2, 3, 4 or 5; R1 and R2 are each independently hydrogen, C1-C4 alkyl or when taken together R1 and R2 may form a ring in which R1R2 are represented by the structure -(CH2)m- where m is an integer of 2, 3, 4 or 5; R3 is cyano, <IMAGE> CH2OR8 or CH(OR9)2; Q is OH, OR4 or NR5R6; A is O, NOR5, NCOR5, NNR5R6 or NNHCONH2; R7 is hydrogen, C1-C4 alkyl or aryl; R8 is hydrogen or C1-C4 alkyl; R9 is C1-C4 alkyl; R4 is C1-C6 alkyl optionally interrupted by O or S or optionally substituted with C1-C4 alkoxy, halogen, hydroxy, C3-C6 cycloalkyl, furyl, or optionally substituted phenyl; C3-C6 alkenyl optionally substituted with one or two C1-C3 alkoxy, halogen, substituted phenyl or C3-C6 cycloalkyl; C3-C6 alkynyl optionally substituted with C1-C4 alkoxy or halogen; C3-C6 cycloalkyl; ammonium; C1-C6 dialkylammonium; C1-C6 trialkylammonium; a metal cation; or a moiety of formula <IMAGE> R5 and R6 each independently represent hydrogen, C1-C6 alkyl, phenyl or halophenyl; the benzotriazole N-oxide or N-methosulfate; and when R1 or R2 is C1-C4 alkyl, the optical isomer thereof; with the proviso that when M is C-X in formula I, wherein X is hydrogen, halogen, nitro, cyano or C1-C4 haloalkyl, the benzotriazole is substituted in the 6 position by aryloxy, n is O, R3 is <IMAGE> and R7 is C1-C4 alkyl, then R and R1 cannot be hydrogen or C1-C4 alkyl. The invention is further directed to methods for the preparation of the aryloxy benzotriazole compounds.
