1-Azinyl-tetraozolinones of the following formulae (I) and (II):
wherein
R1 and R2are independently represent alkyl, haloalkyl, cycloalkyl, alkenyl, haloalkenyl, alkynyl or optionally substituted phenyl, or
R1 and R2,together with the nitrogen atom to which they are bonded, may form a 5- or 6-membered heterocyclic ring which may optionally contain a further heteroatom, and said heterocyclic ring may optionally be benzo-condensed and/or be substituted by one or more of C1-4 alkyl(s), and
R3is a 6-membered heterocyclic aromatic group consisting of carbon atoms and 2 or 3 nitrogen atoms, which may optionally be substituted by halogen, C1-4 alkyl, C1-4 alkoxy, C1-4 alkylthio, di(C1-4 alkyl)amino or phenyl.
The compounds of the formula (I) exhibit an excellent herbicidal activity and the compounds of the formula (II) are useful as starting materials in the production of the compounds of the formula (I).
下式(I)和(II)的 1-氮基四唑啉酮:
其中
R1 和 R2 独立地代表烷基、卤代烷基、环烷基、烯基、卤代烯基、炔基或任选取代的苯基,或
R1 和 R2 与它们所结合的氮原子一起,可以形成一个 5 或 6 元杂环,该杂环可以选择性地包含另一个杂原子,并且所述杂环可以选择性地由苯并缩合和/或被一个或多个 C1-4 烷基取代,以及
R3 是由碳原子和 2 或 3 个氮原子组成的 6 元杂环芳香基团,可任选被卤素、C1-4 烷基、C1-4 烷氧基、C1-4 烷硫基、二(C1-4 烷基)氨基或苯基取代。
式(I)化合物具有优异的除草活性,式(II)化合物可作为生产式(I)化合物的起始原料。
