    • 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  or their acid addition salts with an inorganic or organic acid with thiocyanate of the formula Y-SCN  (III)  in which Y represents sodium, potassium or ammonium in the presence of a diluent and, if appropriate, in the presence of a catalyst and b) reacting the resulting thiosemicarbazide 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 thiosemicarbazide derivatives of the formula (IV) are novel.
    • 根据新的方法,可以制备甲醛的三唑啉酮衍生物,其中R1和R2各自如描述中所定义,a)使下式的肼衍生物或其酸加成盐与无机或有机酸与式 其中Y代表钠,钾或铵,在稀释剂存在下,如果合适的话,在催化剂存在下,和b)使所得到的式的氨基硫代氨基脲衍生物与甲酸反应,如果合适的话,在催化剂存在下,如果合适 在稀释剂存在下。 式(IV)的硫代氨基脲衍生物是新颖的。

    • According to a novel process, triazolinethione derivatives of the formula in which R1 and R2 are 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 &agr;) with oxidizing agents, if appropriate in the presence of a catalyst and in the presence of a diluent, or &bgr;) with formic acid. The triazolidinethiones of the formula (IV) are novel.
    • 根据一个新方法,R1和R2各自如说明书中所定义的式的三唑啉酮衍生物可以通过以下方法制备:a)使下式的肼衍生物与式(X)的甲醛和硫氰酸酯反应,其中X代表钠,钾或铵, 在存在稀释剂的情况下,如果合适的话,在酸的存在下,和b)如果合适的话,在催化剂的存在下和在稀释剂的存在下,将所得到的式e)的三唑烷硫酮与氧化剂反应, 式(IV)的三唑烷硫代乙烯是新的。
