1-Cycloalkenyltetrazolinone derivatives of the following formulae (I) and (II):
wherein
R1represents cycloalkenyl which may optionally be substituted by halogen or C1-4 alkyl, or bicycloalkenyl which may optionally be substituted by halogen or C1-4 alkyl, and
R2 and R3each independently represents alkyl, cycloalkyl, phenyl, substituted phenyl (said substituent being selected from nitro, cyano, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy and alkylthio), alkenyl or alkynyl,
or
R2 and R3may optionally form, together with N-atom to which they are bonded, a 5- or 6-membered heterocyclic ring, said heterocyclic ring may optionally be benzo-condensed and/or be substituted by C1-4 alkyl.
The compounds of formula (I) exhibit an excellent herbicidal activity and the compounds of formula (II) are useful as intermediate compounds in the production process of the compounds of the formula (I).
下式(I)和(II)的 1-环烯基四唑啉酮衍生物:
其中
R1 代表可任选被卤素或 C1-4 烷基取代的环烯基,或可任选被卤素或 C1-4 烷基取代的双环烯基,以及
R2 和 R3 各自独立地代表烷基、环烷基、苯基、取代苯基(所述取代基选自硝基、氰基、卤素、烷基、卤代烷基、烷氧基、卤代烷氧基和烷硫基)、烯基或炔基、
或
R2 和 R3 可选择与它们所结合的 N 原子一起形成一个 5 或 6 元杂环,所述杂环可选择为苯并缩合和/或被 C1-4 烷基取代。
式(I)化合物具有优异的除草活性,式(II)化合物可作为式(I)化合物生产过程中的中间化合物。
