Abstract

Substituted 1-phenyl-3-methyl-pyrrolidinediones of the general formula: ##STR1## in which R may represent fluorine, chlorine, bromine, iodine, CN, SCN or methanesulfonyl, Z represents one or more of the same or different substituents selected from fluorine, chlorine, bromine, iodine, NO.sub.2, CN, SCN, sulfamoyl, phenoxy, an alkyl having from 1 to 3 carbon atoms, a halogenalkyl having from 1 to 3 carbon atoms and 1 to 7 halogen atoms selected from fluorine, chlorine or bromine, an alkyloxy having from 1 to 3 carbon atoms, a halogenalkoxy having from 1 to 3 carbon atoms and 1 to 4 halogen atoms selected from the group consisting of fluorine, chlorine and bromine, an allyloxy or ethoxycarbonyl, and n is 0 or an integer from 1 to 4 with the following types of substitutions: 2-, 4-, 2,3-, 2,4-, 2,5-, 2,6-, 3,4-, 2,3,4-, 2,3,5-, 2,3,6-, 2,4,5-, 2,4,6-, 3,4,5-, 2,3,4,5-, 2,4,5,6- and 2,3,5,6-. The invention also relates to a process for making the compounds, which are active ingredients of fungicidal agents.
