A METHOD OF NEW THIOCOMPOUNDS PRODUCTION AND FUNGICIDE AND BACTERICIDE

摘要

The invention relates to new thio compounds of the general formulawhereinR is an alkyl group substituted or not substituted with halogen and having 1-12 carbon atoms, an alkenyl or alkynyl group having 2-4 carbon atoms, an alkadienyl group having 3 or 4 carbon atoms or a substituted or unsubstituted phenyl or phenyl(C₁-C₄)alkyl group;R, is a cyano group, a formyl group, an alkylcarbonyl or alkoxycarbonyl group substituted or unsubstituted with halogen and having 2-5 carbon atoms, a substituted or unsubstituted benzoyl group, or an alkylsulphonyl group having 1-4 carbon atoms;R₂ is a hydrogen atom, a halogen atom, an amino group unsubstituted or substituted with one or two group selected from C₁-C₄ alkyl and C₂-C₅ alkylcarbonyl, an amino group forming part of a heterocyclic ring which may comprise 1 or 2 additional heteroatoms selected from N, 0 and S, an alkyl or alkoxy group having 1-4 carbon atoms and optionally substituted with C₂-C₅ alkylcarbonyl, or a substituted or unsubstituted phenyl, phenoxy or phenylthio group;or whereinR, and R_z, together with the vinylene group to which they are bound, constitute a substituted or unsubstituted phenyl group;X is a cyano group or a formyl group;n is 1 or 2;Y is an alkylthio group having 1-4 carbon atoms; andZ is a hydrogen atom, a halogen atom, a nitro group, or an alkyl or alkoxy group having 1-4 carbon atoms and optionally substituted with halogen;or wherein Y and Z together constitute a sulphur atom; with the proviso that, when Y and Z do not together constitute a sulphur atom, R₁ and R_z, together with the vinylene group to which they are bound, constitute a substituted or unsubstituted phenyl group.;The new compounds show a fungicidal and/or bactericidal activity and may be used in particular against plantpathogenic seed fungi and soil fungi and/or bacteria.
