ABSTRACT:
A process for producing 1,2,4-triazolin-5-one derivatives represented by the general formula (I) ##STR1## wherein R is a haloalkyl group of 1 to 5 carbon atoms and R.sup.1 is a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, an alkyl group of 1 to 6 carbon atoms having halogen atom substituents, a cycloalkyl group of 3 to 6 carbon atoms, a cycloalkyl group of 3 to 6 carbon atoms having halogen atom substituents, a cyanoalkyl group of 2 to 4 carbon atoms, an alkenyl group of w to 6 carbon atoms, an alkynyl group of 2 to 6 carbon atoms, a lower alkoxyalkyl group of 2 to 6 carbon atoms, a lower alkylthioalkyl group of 2 to 8 carbon atoms, a lower alkylsufinylalkyl group of 2 to 6 carbon atoms, a lower alkylsufonylalkyl group of 2 to 6 carbon atoms, a lower alkoxyalkoxyalkyl group of 3 to 8 carbon atoms, a hydroxycarbonylalkyl group of 2 to 3 carbon atoms, a lower alkoxycarbonylalkyl group of 3 to 6 carbon atoms, a benzylgroup, a benzyl group having 1 to 2 substituents (selected from a halogen atom, a lower alkyl group of 1 to 3 carbon atoms, a lower alkoxy group of 1 to 3 carbon atoms, a nitro group, a lower alkoxycarbonyl group of 2 to 4 carbon atoms, a hydroxycarbonyl group and a phenoxy group), an alpha-methylbenzyl group or a phenethyl group.
