Novel 1,3,4-oxadiazoline-5-one derivatives, their preparation and the insecticidal compositions in which they are present are disclosed. The novel 1,3,4-oxadiazoline-5-one derivatives correspond to the formula: ##STR1## in which: X represents a halogen atom, R.sub.1, R.sub.2 and R.sub.3, which may be identical or different, each represent a hydrogen atom or an alkyl radical containing from 1 to 3 carbon atoms, R.sub.4 represents a halogen atom, an alkyl radical containing from 1 to 3 carbon atoms or an alkoxy radical containing from 1 to 3 carbon atoms, and n represents an integer which is 0, 1, 2, 3 or 4, with the proviso that if n is 2, 3 or 4, the substituents R.sub.4 are identical or different. These compounds are useful as agricultural insecticides.
本发明揭示了新的1,3,4-噁二唑啉-5-酮衍生物、它们的制备方法以及含有它们的杀虫剂组合物。这些新的1,3,4-噁二唑啉-5-酮衍生物对应于以下式子:##STR1## 其中:X代表卤素原子,R.sub.1、R.sub.2和R.sub.3可以相同也可以不同,分别代表氢原子或含有1至3个碳原子的烷基基团,R.sub.4代表卤素原子、含有1至3个碳原子的烷基基团或含有1至3个碳原子的烷氧基基团,n代表整数0、1、2、3或4,但若n为2、3或4,则取代基R.sub.4可以相同或不同。这些化合物可用作农业杀虫剂。
