Abstract
The present invention relates to a process for manufacturing substituted triazolinones, which are intermediates in the preparation of herbicidally active compounds. In particular, this invention relates to the reaction of an isothiocyanate with an alkanol to produce a thionocarbamate intermediate product; alkylation of the intermediate product, reaction of the alkylated intermediate with and alkoxycarbobyl or aryloxycarbonyl hydrazine and reaction of the resultant compound with a base to produce a substituted triazolinone. In this context the terms “alkanol” and “alkylation” represent generic terms and thus, include the use of alkanols and alkylating agents having an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group or an arylalkyl group.
