Safeners against phytotoxic side effects of pesticides in crop plants are compounds of the formula (I) and salts thereof (see formula I) where R1 is hydrogen, a hydrocarbon radical, a hydrocarbonoxy radical, a hydrocarbonthio radical or a heterocyclyl radical, each of the last-mentioned 4 radicals being unsubstituted or substituted by one or more identical or different radicals selected from the group consisting of halogen, cyano, nitro, amino, hydroxyl, carboxyl, formyl, carboxamide, sulfonamide and radicals of the formula -Z a-R a, R2 is hydrogen or (C1-C4)-alkyl, or R1 and R2 together with the group of the formula -CO-N- are the radical of a 3- to 8-membered saturated or unsaturated ring, R3 to R5, R a and Z a represent various radicals, n is an integer from 0 to 4, and m is an integer from 0 to 5. Some of the compounds of the formula (I) are novel, and a process for preparing such novel compounds is also provided.
Des phytoprotecteurs utilisés contre des effets secondaires phytotoxiques de pesticides dans des plantes cultivées sont des composés de la formule (I) et leurs sels. Dans cette formule, R<1> désigne hydrogène, un reste hydrocarbure, un reste hydroxy d'hydrocarbure, un reste thio d'hydrocarbure ou un reste hétérocyclyle, chacun des 4 derniers restes cités n'étant pas substitué ou étant substitué par un ou plusieurs restes identiques ou différents du groupe halogène, cyano, nitro, amino, hydroxy, carboxy, formyle, carbonamide, sulfonamide et des restes de la formule -Z<a>-R<a>, R<2> désigne hydrogène ou alkyle (C1-C4), ou R<1> et R<2> désignent conjointement avec le groupe de la formule -CO-N- le reste d'un composé cyclique saturé ou non saturé ayant entre 3 et 8 chaînons, et R<3> à R<5>, n et m ont la notation mentionnée dans la revendication 1. Ces composés peuvent être obtenus selon le procédé défini dans la revendication 8.
