Abstract

Herbicidal halogenated sulphanylaminocarbonyl-triazolinones of the formula (see formula I) in which R1 represents hydrogen, hydroxyl or amino, or repre-sents an optionally substituted radical from the group consisting of alkyl, alkenyl, alkynyl, cyclo-alkyl, aralkyl, aryl, alkoxy, alkenyloxy, alkyl-amino, cycloalkylamino and dialkylamino, R2 represents halogen and R3 represents an optionally substituted radical from the group consisting of alkyl, aralkyl, aryl and heteroaryl, and salts thereof.

Description

The invention relates to new halogenated sul-phonylaminocarbonyltriazolinones, to several processes for their preparation, and to their use as herbicides.
It is known that certain substituted aminocarbon ylimidazolinones, such as, for example, 1-isobutylamino carbonyl-2-imidazolidinone (isocarbamid), have herbicidal properties (cf. R. Wegler, Chemie der Pflanzenschutz- and 5chadlingsbekampfungsmittel [Chemistry of Plant Protec tion Agents and Pesticides], Vol. 5, p. 219, Springer Verlag, Berlin-Heidelberg-New York, 1977). However, the action of this compound is not satisfactory in all respects.
The new halogenated sulphonylaminocarbonyl-triazolinones of the general formula (I) R3-SOZ-NH-CO-Nr\N-R1 (I) ~R2 in which R1 represents hydrogen, hydroxyl or amino, or repre-sents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cyclo-alkyl, aralkyl, aryl, alkoxy, alkenyloxy, al 1 amino, cycloalkylamino and dialkylamino, R2 represents halogen and R3 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and Le A 27 155 _ 1 heteroaryl, as well as salts of compounds of the formula (I) have now been found.
The new halogenated sulphonylaminocarbonyltri-azolinones of the general formula (I) are obtained when a) halogenated triazolinones of the general formula (II) HN~N-R1 (II) in which R' and RZ have the abovementioned meanings are reacted with sulphonyl isocyanates of the general formula (III) R3-SOZ-N=C=0 ( I I I ) in which I5 R3 has the abovementioned meaning, if appropriate in the presence of a diluent, or when b) halogenated triazolinone derivatives of the general formula (IV) Z-CO-N~N-R1 (IV) ~R2 Le A 27 155 in which Rr and Rz h ve the abovementioned meanings and Z represents halogen, alkoxy, aralkoxy or aryloxy are reacted with sulphonamides of the general formula (V) R3-S~z-~z f V) in which R3 has the abovementioned meaning, if ,appropriate in the presence of an acid acceptor ld and if appropriate in the presence of a diluent, or when c) halogenated triazolinones of the general formula (II) O
HN~N-R1 (II) ~R2 in which R' and Rz have the abovementioned meanings are reacted with sulphonamide derivatives of the general formula (VI) R3-sot-rrx-c~-z ~ vI ~
2a in which R3 has the abovementioned meaning and Z represents halogen, alkoxy, aralkoxy or Le A 27 155 - 3 aryloxy, if appropriate in the presence of an acid acceptor and if appropriate in the presence of a diluent, and, if desired, salts are formed by customary methods from the compounds of the formula (I) prepared by process (a), (b) or (c).
The new halogenated sulphonylaminocarbonyltri-azolinones of the general formula (I) and their salts are distinguished by a powerful herbicidal activity.
Surprisingly, the new compounds of the formula (I) have a considerably better herbicidal action than the known herbicide 1-isobutylaminocarbonyl-2-imidazolidinone (isocarbamid), which has a similar structure.
The invention preferably relates to compounds of the formula (I) in which R1 represents hydrogen, hydroxyl or amino, or repre-sents C1-C6-alkyl which is optionally substituted by fluorine, chlorine, bromine, cyano, C1-Ca-alkoxy, C1-Ca-alkylcarbonyl or C1-Ca-alkoxy-carbonyl, or represents C3-Cs-alkenyl or C3-C6-alkinyl, each of which is optionally substituted by fluorine, chlor-ine and/or bromine, or represents C3-C6-cycloalkyl which is optionally substituted by fluorine, chlor-ine, bromine and/or C1-Ca-alkyl, or represents phenyl-Cl-C3-alkyl which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C1-Ca-alkyl, trifluoromethyl, C1-Ca-alkoxy and/or C1-Ca-alkoxy-carbonyl, or represents phenyl which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C~-Ca-alkyl, trifluoromethyl, he A 27 155 C1-C4-alkoxy, fluorine- and/or chlorine-substituted C1-C3-alkoxy, C~-C4-alkylthio, fluorine- and/or chlorine-substituted C1-C3-alkylthio, Cl-C4-alkylsul-phinyl, C1-C4-alkylsulghonyl and/or Cl-C,,-alkoxy-carbonyl, or represents C1-Cs-alkoxy which is option-ally substituted by fluorine, chlorine, cyano, C1-C4-alkoxy or Cl-C,,-alkoxy-c _rbonyl, or represents C~-C4-alkenyloxy, or represents fluorine-, cyano-, phenyl-, C1-Ca-alkoxy- or C1-C4-alkoxy-carbonyl-ZO substituted Cl-C4-alkylamino, C3-C6-cycloalkylamino, or represents di- ( C1-C,,-alkyl ) -amino, RZ represents fluorine, chlorine, bromine or iodine and R3 represents the group ~ , where R° and RS are identical or different and represent hydrogen, fluorine, chlorine, bromine, iodine, nitro, C1-C6-alkyl (which is optionally substi-tuted by fluorine, chlorine, bromine, cyano, carboxyl, C1-C4-alkoxycarbonyl, C1-C4-alkyl-amino-carbonyl, di-(Cl-C4-alkyl)amino-carbonyl, hydroxyl, C1-C,,-alkoxy, formyloxy, C,-Cw-alkyl-carbonyloxy, C1-C4-alkoxy-carbonyloxy, C~-C4-alkylamino-carbonyloxy, C1-C4-alkylthio, C1-C4_ alkylsulphinyl, Cl-C4-alkylsulphonyl, di- ( C1-C,,-alkyl)-aminosulphonyl, C3-C6-cycloalkyl or phenyl), or represent CZ-Cs-alkenyl (which is optionally substituted by fluorine, chlorine, bromine, cyano, C1-C4-alkoxy-carbonyl, carboxyl or phenyl ) , or represent C2-C6-alkinyl (which is Le A 27 155 - 5 -~~2~~~~
