摘要:
A process is disclosed for the preparation of the herbicide ethyl &agr;-2-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-4-fluorobenzenepropionate by the simultaneous diazotization of 4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo-1-(5-amino-2-fluoro-4-chloro-phenyl)-1H-1,2,4-triazole (the Amine) and arylation of ethyl acrylate with the diazotized Amine. In the process the following reagents are added in sequence and, under specified conditions, to a cooled, stirred solution of the Amine in acetone: cuprous chloride, hydrochloric acid, ethyl acrylate, and sodium nitrite.

According to a novel process, it is possible to prepare triazolinethione derivatives of the formula in which R1 and R2 are each as defined in the description by a) reacting hydrazine derivatives of the formula with carbonyl compounds of the formula in which R3 and R4 are each as defined in the description with potassium thiocyanate, sodium thiocyanate or ammonium thiocyanate, if appropriate in the presence of a diluent and if appropriate in the presence of an acid, and b) reacting the resulting triazolidinethione derivatives of the formula with formic acid, if appropriate in the presence of a catalyst and if appropriate in the presence of a diluent. The triazolidinethione derivatives of the formula (V) are novel.
摘要:
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.
