Abstract

Préparation de N-sulfonyl-aryloxy benzamide (I) par réaction d'acide aryloxybenzoique avec un sulfonyl isocyanate ou isothiocyanate. Le procédé selon l'invention se distingue par la simplicité du mode de récupération du produit final car celui-ci est généralement insoluble dans le milieu de réaction chaud et s'en sépare en cristallisant sous une forme pure, en sorte que cette récupération se réduit essentiellement à une filtration. On peut aussi faciliter cette filtration par addition d'un non solvant. Les dérivés ainsi préparés sont destinés à servir en tant que herbicides.
