    • A process is described for preparing 1-aryltriazolinones of formula (I) useful in the production of commercial herbicides, by: i) carbonylating an amidrazone of formula (A) with one or more carbonylating agent, or ii) condensing a hydrazonoyl derivative of formula (A) with one or more ring-forming agent in formula (A), where W, X, Y, Z, and R are fully described herein. Preferred are those where W is halogen or -NHR where R is hydrogen or haloalkyl; X and Y are independently selected from hydrogen, chloro, or fluoro; Z is hydrogen, bromo, iodo, nitro, amino, or methylsulfonylamino; and R is methyl. Certain compounds of formula (A) are novel compositions of matter. The process as described herein has utility in providing compounds of formula (I) in unexpectedly high yield and purity.
    • 描述了用于制备可用于生产商业除草剂的式(I)的1-芳基三唑啉酮的方法,其通过:i)用一种或多种羰基化剂将式(A)的氨基腙羰基化,或者ii)将式(I)的亚肼基衍生物 (A)与式(A)中的一种或多种成环剂反应,其中W,X,Y,Z和R 1在本文中完全描述。 优选W为卤素或-NHR(其中R为氢或卤代烷基)的那些; X和Y独立地选自氢,氯或氟; Z是氢,溴,碘,硝基,氨基或甲基磺酰基氨基; 并且R 1是甲基。 某些式(A)化合物是新颖的物质组合物。 如本文所述的方法可用于提供意想不到的高收率和纯度的式(I)化合物。
