Patent
CA 2263093
The present invention pertains to substituted 2-phenylpyridine I and the salts thereof of formula (I), where R1 = SH, SO2NH2, C1-C2-alkylthio, C1-C6-alkyl- sulfinyl, C1-C6-akylsulfonyl, C1-C6alkylaminosulfonyl, Di-(C1- C6alkyl)aminosulfonyl; R1, R3 = H, halogen; R4 = CN, OH, halogen, C1-C6- alkoxy, possibly substituted OCH2-phenyl and R5 have the meanings given in the description. The invention also relates to: the use of compounds (I) as herbicides or as plant dessicating/defoliating agents, the herbicides and the plant dessicating/defoliating agents containing compounds (I) as actives substances, the processes for controlling undesirable plant growth and for dessicating/defoliating plants using compounds (I), the processes for producing compounds (I), herbicides and plant dessicating/defoliating agents by compounds (I), as well as the intermerdiate products of formulae (IIa, V and VI).
La présente invention concerne la phénylpyridine substituée en 2 et ses sels (I), où R?1¿ = SH, SO¿2?OH, SO¿2?C1, SO¿2?NH¿2?, C¿1?-C¿6?-alkylthio, C¿1?-C¿6?-alkyl-sulfinyle, C¿1?-C¿6?-alkylsulfonyle, C¿1?-C¿6?-alkylaminosulfonyle, Di-(C¿1?-C¿6?-alkyl)aminosulfonyle; R?2¿, R?3¿ = H, halogène; R?4¿ = CN, OH, halogène, C¿1?-C¿6?-alkoxy, OCH¿2?-phényle éventuellement substitué; et ont les significations indiquées dans la revendication 1. En outre, l'invention concerne: l'utilisation des composés (I) comme herbicides ou comme agents de dessiccation/défoliation des plantes, les herbicides et les agents de dessiccation et/ou défoliation contenant les composés (I) comme substances actives, les procédés de lutte contre les plantes parasites et de dessiccation/défoliation de plantes par les composés (I), les procédés de production des composés (I), d'agents herbicides et d'agents de dessiccation et/ou défoliation de plantes par les composés (I), ainsi que les composés intermédiaires correspondant aux formules (IIa, V et VI).
