    • The invention relates to a novel method for producing triazolinthion derivatives of formula (I) in which R?1 and R2¿ have the meanings given in the description. To this end, a) Hydrazine derivatives of formula (II) or addition salts thereof are reacted with an inorganic or organic acid with thiocyanate of formula (III) Y-SCN in which Y represents sodium, potassium or ammonium, said reaction is carried out in the presence of a diluting agent and optionally in the presence of a catalyst; b) the formed thiosemicarbazide derivatives of formula (IV) are reacted with formic acid optionally in the presence of a catalyst and optionally in the presence of a diluting agent. The thiosemicarbazide derivatives of formula (IV) are novel.
    • 本发明涉及一种制备式(I)三唑啉酮衍生物的新方法,其中R 1和R 2具有在说明书中给出的含义。 为此,a)式(II)的肼衍生物或其加成盐与无机酸或有机酸与其中Y代表钠,钾或铵的式(III)Y-SCN的硫氰酸酯反应,所述反应进行 在稀释剂存在下并任选在催化剂存在下进行; b)将所形成的式(IV)的氨基硫脲衍生物与甲酸任选在催化剂存在下并任选在稀释剂存在下反应。 式(IV)的氨基硫脲衍生物是新颖的。
