Substituted guanidine derivatives

A plant growth regulating compound of the formula STR1 in which R2 is an optionally substituted nitrogen heterocyclic radical, R3 is hydrogen, alkyl, cycloalkyl, alkenyl, alkinyl or aralkyl, and R4 is hydrogen, or if R3 is not hydrogen R4 may be hydroxyl or a variety of radicals, or R3 and R4 together may form a ring, or an acid adduct thereof.

Process for the preparation of N'-sulphonyl- and N',N"-bis-sulphonyl-guanidine derivatives

A process for the preparation of a guanidine derivative of the formula STR1 in which R1 represents hydrogen or the radical R5 --S(O)m --, m represents the numbers zero, 1 or 2 and R5 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, R2 represents a six-membered aromatic heterocyclic structure which contains at least one nitrogen atom and is substituted, and R8 represents an optionally substituted radical from the series comprising C1 -C6 -alkyl, alkenyl, alkinyl, cycloalkyl, phenylalkyl and aryl, which comprises reacting a guanidine derivative of the formula STR2 with one or two molar equivalent(s), respectively, of a halogen/sulphur compound of the formula in which X1 represents fluorine, chlorine or bromine. The compounds are herbicidally active.

N'-(substituted-1,3,5-triazin-2-yl)-N"-amino-N"'-(substituted-benzenesulphonyl)-guanidines as herbicides

A selective herbicide of the formula STR1 in which m is 0, 1 or 2, R5 is an organic radical, R3 is hydrogen or an organic radical, R9 is hydrogen or an optionally substituted alkyl radical, R10 is an organic radical or forms a ring with R9, R40 and R41 are alkyl or alkoxy, and M is hydrogen or a metal or ammonium radical, or an acid adduct thereof.

N'-(substituted-pyrimidin-2-yl)-N"-amino-N"'-(substituted-benzenesulphonyl)-guanidines as herbicides

Herbicidally active guanidine derivatives of the formula STR1 in which m represents the numbers zero, 1 or 2, R5 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, R2 represents a pyrimidin-2-yl radical which is substituted by halogen, amino, cyano or formyl and/or by optionally substituted radicals from the series comprising alkyl, alkoxy, alkylamino, dialkylamino, alkylcarbonyl and alkoxycarbonyl, R3 represents hydrogen, an optionally substituted radical from series comprising alkyl, cycloalkyl, alkenyl, alkinyl and aralkyl, R9 represents hydrogen or optionally substituted alkyl and R10 represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, heteroaryl, alkyl- or alkoxycarbonyl and alkyl- or arylsulphonyl, or R9 and R10 together represent alkanediyl which is optionally interrupted by an oxygen atom; and M represents hydrogen, one equivalent of a metal, or an ammonium radical which is optionally substituted by alkyl, alkenyl, alkinyl and/or aralkyl, or--in the case in which M is bonded to the same nitrogen atom as R2 --also represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl and aralkyl, or acid adducts thereof.

N'-(substituted-1,3,5-triazin-2-yl)-N"-substituted-N",N"'-bis-(substituted-benzenesulphonyl)-guanidines as herbicides

Herbicidally active novel N,N'-bis-sulphonyl guanidines of the formula STR1 in which M is hydrogen, a metal or an ammonium radical, and R4, R5, R40 and R41 are various organic radicals.

N'-(substituted-pyrimidin-2-yl)-N"-substituted-N",N"'-bis-(substituted-benzenesulphonyl)-guanidines as herbicides

Guanidine derivatives of the formula STR1 in which R2 represents a six-membered aromatic heterocyclic structure which contains at least one nitrogen atom and is substituted by halogen, amino, cyano or formyl and/or by optionally substituted radicals from the series comprising alkyl, alkoxy, alkylamino, dialkylamino, alkylcarbonyl and alkoxycarbonyl, and/or is optionally fused, R3 represents hydrogen, an optionally substituted radical from the series comprising alkyl, cycloalkyl, alkenyl, alkinyl and aralkyl, or the radical --S(O)n --R6, the other radicals can have varied meanings, and acid adducts and salts thereof, which possess herbicidal and plant growth regulating activity.
