摘要

Sulfenylated acylhydrazones having the formula <CHEM> wherein R<1> is hydrogen, cyano, straight or branched chain lower (C1-C4) alkyl optionally substituted with imidazolyl, triazolyl or one or more of the same or different halo; or phenyl optionally substituted with one or more of the same or different halo, nitro, cyano, (C1-C4)-allcyl or (C1-C4)-alkoxy; R<2> is hydrogen; straight or branched chain (C1-C11)-alkyl optionally substituted with imidazolyl, triazolyl, or one or more of the same or different halo; (C1-C4)-alkoxy; (C1-C4)-thioalkyl; (C2-C6)-alkenyl optionally substituted with one or more of the same or different halo; heterocyclic optionally substituted with one or more of the same of different halo or nitro; phenyl optionally substituted with one or more of the same or different halo; (C1-C4)-alkyl, (C1-C4)-alkoxy or nitro; or phenalkyl where the alkyl moiety contains one to four carbon atoms and the phenyl ring is optionally substitued with one or more of the same or different halo (chloro, fluoro, bromo or iodo), cyano, nitro, (C1-C4)-alkyl, (C1-C4)-alkoxy, or (C1-C4)-haloalkyl; Z is (C1-C4)-haloalkyl; and A is phenyl optionally substituted with one or more of the same or different halo, nitro, cyano, hydroxy, (C1-C6)-alkyl, (C1-C6)-haloalkyl, (C1-C6)-thioalkyl, (C1-C6)-alkoxy, (C1-C6)-carbalkoxy, allyloxy, (C1-C6)-alkanoyloxy, (C1-C6)-alkylamino, (C1-C6)-dialkylamino or benzyloxy; thiorphenyl optionally substituted with one or more of the same or different nitro or halo; furyl optionally substituted with one or more of the same or different nitro or halo; pyridyl; or naphthyl; and compositions containing these compounds exhibit biocidal and plant fungicidal activity.
