Abstract
The present invention relates to a novel process for preparing triazolinones of the general formula (I) ##STR1## in which R.sup.1 represents halogenoalkyl, and PA1 R.sup.2 represents hydrogen, hydroxyl or amino, or represents alkyl, alkenyl, alkinyl, alkoxy, alkylamino, dialkylamino, cycloalkyl, cycloalkylalkyl, phenyl or phenylalkyl which are in each case optionally substituted, and also to novel intermediates for preparing these triazolinones and to processes for preparing the intermediates themselves.
