ABSTRACT:
2-Arylmethyliminopyrazines of the formula I ##STR1## in which R.sub.1 is SR.sub.2 ; OR.sub.2 ; O--CHR.sub.10 R.sub.2 ; N(R.sub.3)(CHR.sub.10 R.sub.4); N(R.sub.11)(CHR.sub.10 R.sub.4) or NR.sub.3 R.sub.4 ; R.sub.2 is C.sub.1 -C.sub.10 - alkyl which is unsubstituted or substituted by hydroxyl, mercapto, C.sub.1 -C.sub.4 -alkoxycarbonyl, mercaptoalkoxy, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylcarbonyl, mono- or di-C.sub.1 -C.sub.4 -alkylamino, C.sub.1 -C.sub.4 -haloalkoxy, tri-(C.sub.1 -C.sub.4 -alkoxy)-silyl, cyano, nitro or phenyl; C.sub.1 -C.sub.4 -haloalkyl; C.sub.3 -C.sub.8 -alkenyl; (3-methyl-oxetan-3-yl)methyl; C.sub.3 -C.sub.8 -alkynyl; or a radical from the group comprising phenyl, benzyl, C.sub.3 -C.sub.7 -cycloalkyl, furanyl or furfuryl which is unsubstituted or mono-, di- or trisubstituted by identical or different substituents from the group comprising halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkylcarbonyl, nitro, C.sub.1 -C.sub.4 -alkoxy and C.sub.1 -C.sub.4 -haloalkyl; R.sub.3 and R.sub.4 independently of one another are hydrogen; a phenyl or benzyl radical which is unsubstituted or mono-, di-, tri- or tetrasubstituted by identical or different substituents from the group comprising halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkylcarbonyl, nitro, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkylthio and C.sub.1 -C.sub.4 -haloalkylthio; C.sub.1 -C.sub.8 -alkyl; or C.sub.3 -C.sub.6 -cycloalkyl; or R.sub.3 and R.sub.4, together with the nitrogen atom, form a saturated 5- or 6-membered heterocyclic ring which contains up to two heteroatoms from the group comprising N, O and S and can be mono- or disubstituted by C.sub.1 -C.sub.4 -allkyl; R.sub.5 is hydrogen; halogen; C.sub.1 -C.sub.8 -alkyl; C.sub.1 -C.sub.4 -alkoxy; C.sub.1 -C.sub.4 -haloalkyl; nitro; cyano; C.sub.1 -C.sub.4 -haloalkoxy; phenylthio; di-C.sub.1 -C.sub.4 -alkylamino; phenyl; or is phenoxy which is unsubstituted or substituted by the radicals R.sub.8 and R.sub.9 ; and R.sub.6, R.sub.7, R.sub.8 and R.sub.9 independently of one another are hydrogen; halogen; C.sub.1 -C.sub.8 -alkyl; C.sub.1 -C.sub.4 -haloalkyl; C.sub.1 -C.sub.4 -alkoxy; C.sub.1 -C.sub.4 -haloalkoxy; nitro; cyano; or di-C.sub.1 -C.sub.4 -alkylamino; and R.sub.10 and R.sub.11 independently of one another are C.sub.1 -C.sub.4 -alkyl; and salts of compounds of the formula I with acids and bases, process for their preparation and herbicidal or plant growth-regulating compositions containing compounds of the formula I.
