Patent

CA 2254784

The invention relates to compounds of the formula (I) and the salts thereof, in which formula A is a (hetero)aromatic or heterocyclic bridge which is connected to the group SO2 via a direct bond or O, S, NH, CH2, or via alkylated NH or alkylated methylene; B is a group with an imino-containing fragment from N = C-N, N = C-S, N = C-O or N = C-C which is bound to A by one of the N-atoms of the fragment; R is H or an aliphatic radical; W is O or S; and X, Y and Z have the definitions given in claim 1. Said compounds are suitable to act as herbicides and plant growth regulators. Preparation, for example in a manner similar to known processes, occurs by way of new intermediate products of the formula (XII) (cf. claims 6 and 10).

L'invention concerne des composés de la formule (I) et leurs sels. Dans ladite formule (I) A représente un pont (hétéro)aromatique ou hétérocyclique qui est relié au groupe SO¿2? par une liaison directe, par un groupe O, S, NH, CH¿2?; B représente un groupe comportant un fragment N=C-N, N=C-S, N=C-O présentant une fonction imino, qui est liée à A avec un des atomes de N du fragment; R représente H ou un reste aliphatique; W représente O ou S; et X, Y et Z correspondent à la définition donnée dans la revendication 1. De tels composés peuvent être utilisés comme herbicides et régulateurs de la croissance végétale. La production de ces composés se fait, par exemple, de façon similaire à des procédés connus, au moyen de nouveaux produits intermédiaires de la formule (XII) (cf. revendications 6 et 10).
