A compound of the formula ##STR58## wherein R.sub.1 is a member selected from the group consisting of substituted or unsubstituted C.sub.1 to C.sub.12 linear- or branched-alkyl, C.sub.5 to C.sub.12 cyclo-alkyl, substituted or unsubstituted C.sub.2 to C.sub.12 linear- or branched-alkenyl or C.sub.5 to C.sub.12 cycloalkenyl and substituted or unsubstituted C.sub.6 to C.sub.14 carbocyclic aryl;

at least one of R.sub.2 and R.sub.3 is morpholino and the other is selected from the group consisting of (1) --OR' in which R' is a member selected from the group consisting of a hydrogen atom, substituted or unsubstituted C.sub.1 to C.sub.12 linear- or branched-alkyl or C.sub.5 to C.sub.12 cyclo-alkyl, substituted or unsubstituted C.sub.2 to C.sub.12 linear- or branched-alkenyl or C.sub.5 to C.sub.12 cyclo-alkenyl and substituted or unsubstituted C.sub.6 to C.sub.14 carbocyclic aryl, (2) --SR' in which R' is as defined above, (3) --N(R').sub.2 in which R' is the same as defined above or the R' groups together with the nitrogen to which they are attached form morpholino, and (4) a halogen atom;
and X is S or O;
the substituent for the substituted alkyl group or the substituted alkenyl group is a member selected from the group consisting of halogen atoms, cyano, nitro, alkoxycarbonyl with the alkoxy moiety containing 1 to 12 carbon atoms, alkoxy of 1 to 12 carbon atoms, carboxyl, alkanoyl of 1 to 12 carbon atoms, alkanoyloxy of 1 to 12 carbon atoms, benzoyloxy, thiocyanato, isothiocyanato, acetamide, acetylthio, phosphono, .beta.-phosphonoethyloxysulfonyl, (CH.sub.3).sub.3.sup.+ N.sup.C1- CH.sub.2 --CH.sub.2 --, phenyl, phenylalkyl of 7 to 14 carbon atoms, and alkylthio with the alkyl moiety containing 1 to 12 carbon atoms;
and with the substituent for the substituted aryl group is a member selected from the group consisting of alkyl of 1 to 6 carbon atoms, halogen atoms, acetyl, acetamido, nitro, cyano, carboxyl, alkoxy of 1 to 6 carbon atoms and hydroxyl;
with the proviso that when X is S, both R.sub.2 and R.sub.3 are not the groups morpholino or --N(R').sub.2 at the same time.

Abstract

at least one of R.sub.2 and R.sub.3 is morpholino and the other is selected from the group consisting of (1) --OR' in which R' is a member selected from the group consisting of a hydrogen atom, substituted or unsubstituted C.sub.1 to C.sub.12 linear- or branched-alkyl or C.sub.5 to C.sub.12 cyclo-alkyl, substituted or unsubstituted C.sub.2 to C.sub.12 linear- or branched-alkenyl or C.sub.5 to C.sub.12 cyclo-alkenyl and substituted or unsubstituted C.sub.6 to C.sub.14 carbocyclic aryl, (2) --SR' in which R' is as defined above, (3) --N(R').sub.2 in which R' is the same as defined above or the R' groups together with the nitrogen to which they are attached form morpholino, and (4) a halogen atom;
and X is S or O;
the substituent for the substituted alkyl group or the substituted alkenyl group is a member selected from the group consisting of halogen atoms, cyano, nitro, alkoxycarbonyl with the alkoxy moiety containing 1 to 12 carbon atoms, alkoxy of 1 to 12 carbon atoms, carboxyl, alkanoyl of 1 to 12 carbon atoms, alkanoyloxy of 1 to 12 carbon atoms, benzoyloxy, thiocyanato, isothiocyanato, acetamide, acetylthio, phosphono, .beta.-phosphonoethyloxysulfonyl, (CH.sub.3).sub.3.sup.+ N.sup.C1- CH.sub.2 --CH.sub.2 --, phenyl, phenylalkyl of 7 to 14 carbon atoms, and alkylthio with the alkyl moiety containing 1 to 12 carbon atoms;
