Aryloxy benzotriazole herbicidal agents and methods for the preparation thereof

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: STR1 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 R1 R2 are represented by the structure --(CH2)m -- where m is an integer of 2, 3, 4 or 5; R3 is cyano, STR2 CH2 OR8 or CH(OR9)2 ; Q is OH, OR4 or NR5 R6 ; A is O, NOR5, NCOR5, NNR5 R6 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 STR3 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 STR4 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.
