Abstract: front page image
(EN)A herbicide containing as the active ingredient an N-(phenylsulfonyl)picolinamide derivative represented by general formula (I) wherein X represents a halogeno, a C¿1-4? alkyl, a C¿1-4? haloalkyl, a C¿1-4? alkoxy, a C¿1-4? haloalkoxy, a (C¿1-4? alkoxy)carbonyl, a [di(C¿1-4? alkyl)amino]sulfonyl, an [N-(C¿1-4? alkyl)-N-(C¿1-4? alkoxy)amino]sulfonyl, a (C¿1-4? alkylamino)sulfonyl, a C¿1-4? alkylthio, a C¿1-4? alkylsulfinyl, a C¿1-4? alkylsulfonyl, or nitro; n is an integer of 0 to 5; Y represents a halogeno, a C¿1-4? alkyl, a C¿1-4? haloalkyl, a C¿1-4? alkoxy, a C¿1-4? haloalkoxy, a C¿1-4? alkylthio, a C¿1-4? haloalkylthio, amino, a C¿1-4? alkylamino, a di(C¿1-4? alkyl)amino, a (C¿1-4? alkoxy) C¿1-4? alkyl, a (C¿1-4? alkylthio) C¿1-4? alkyl, or nitro; and m is an integer of 0 to 4. This active ingredient is synthesized by condensing a substituted picolinic acid with a substituted benzenesulfonamide under dehydration, or by reacting the phenyl ester of a substituted picolinic acid with a substituted benzenesulfonamide in the presence of a basic compound.
(FR)On décrit un herbicide contenant en tant qu'ingrédient actif un dérivé de N-(phénylsulfonyle) picolinamide représenté par la formule (I) dans laquelle X représente un halogéno, un alkyle C¿1-4?, un haloalkyle C¿1-4?, un alcoxy C¿1-4?, un haloalcoxy C¿1-4?, un (alcoxy C¿1-4?)carbonyle, un [di (alkyle C¿1-4?)amino]sulfonyle, un [N - (alkyle C¿1-4?) -N- (alcoxy C¿1-4?) amino]sulfonyle, un (alkylamino C¿1-4?)sulfonyle, un alkylthio C¿1-4?, un alkylsulfynyle C¿1-4?, un alkylsulfonyle C¿1-4?, ou nitro; n représente un entier compris entre 0 et 5; Y représente un halogéno, un alkyle C¿1-4?, un haloalkyle C¿1-4?, un alcoxy C¿1-4?, un haloalcoxy C¿1-4?, un alkylthio C¿1-4?, un haloalkylthio C¿1-4?, amino, un alkylamino C¿1-4?, un di(alkyle C¿1-4?)amino, un (alcoxy C¿1-4?)alkyle C¿1-4?, un (alkylthio C¿1-4?)alkyle C¿1-4?, ou nitro; et m représente un entier compris entre 0 et 4. Pour synthétiser cet ingrédient actif, on condense un acide picolinique substitué avec un benzènesulfonamide substitué dans des conditions de déshydratation, ou bien on fait réagir un ester phénylique d'un acide picolinique substitué avec un benzènesulfonamide substitué en présence d'un composé basique.
