Paragraph 0029-0038, (2020/09/09)
After the reaction, the reaction liquid is filtered, and then the reaction liquid is filtered 2 - 1 - the concentrated reaction -3 - liquid -1 - is 2 - firstly removed -2 - and then the concentrated reaction liquid is subjected to extraction to obtain the upper-layer prothioconazole intermediate phase and the lower aqueous hydrazine hydrate phase. The method has the advantages of mild conditions, simple process operation, convenient post-treatment and high efficiency, and is a green synthesis process. (by machine translation)

According to a novel process, triazolinethione derivatives of the formula in which R1and R2are each as defined in the description, can be prepared by a) reacting hydrazine derivatives of the formula ?with formaldehyde and thiocyanate of the formula X—SCN??(III), ?in which X represents sodium, potassium or ammonium, ?in the presence of a diluent and if appropriate in the presence of an acid, and b) reacting the resulting triazolidinethiones of the formula ?either α) with oxidizing agents, if appropriate in the presence of a catalyst and in the presence of a diluent, or β) with formic acid. The triazolidinethiones of the formula (IV) are novel.
