Compounds of formula (I): ##STR1## (wherein: R.sup.1 represents a hydrogen atom or a halogen atom; R.sup.2 represents a C.sub.1 -C.sub.6 alkyl group; and A represents an oxygen atom, a sulphur atom, a sulphinyl group or a sulphonyl group) have good insecticidal activity coupled with a low toxicity to warm-blooded animals. Compounds in which A represents an oxygen or sulphur atom can be prepared by reacting a corresponding alkali metal alkoxide or mercaptide with the corresponding 3-dimethylcarbamoyloxy-5-halomethylisoxazole derivative, while compounds where A represents a sulphinyl or sulphonyl group may be prepared by oxidizing the corresponding compound wherein A represents a sulphur atom. The compounds may be formulated with conventional insecticidal carriers or diluents and exhibit a synergistic increase in activity when combined with various known organic phosphate and carbamate insecticides.
式(I)化合物:##STR1##(其中:R.sup.1代表氢原子或卤素原子;R.sup.2代表C.sub.1-C.sub.6烷基;A代表氧原子、硫原子、磺酰基或亚磺酰基)具有良好的杀虫活性,同时对温血动物的毒性较低。其中A代表氧原子或硫原子的化合物可通过将相应的碱金属醇盐或巯基盐与相应的3-二甲基氨基甲酰氧基-5-卤甲基异噁唑衍生物反应制备,而A代表亚磺酰基或磺酰基的化合物可通过氧化A代表硫原子的相应化合物制备。这些化合物可以与传统的杀虫剂载体或稀释剂配制,当与各种已知的有机磷和氨基甲酸酯类杀虫剂结合时,表现出协同增强的活性。
