The invention relates to two oxime ether or ester derivatives with insecticidal activity and an application thereof. The two derivatives have the structural formulas shown in the specification of the invention. The preparation method comprises the following steps of: carrying out an acylation reaction or an alkylation reaction on substituted acyl halide or halide and aromatic aldehyde (ketone) oxime under the condition of dichloromethane or DMF (Dimethylformamide) to obtain a derivative I; and carrying out addition reaction on various substituted aromatic aldehydes (ketones) oxime and the prepared aryl isocyanate or isorhodanic ester to obtain a derivative II. The derivatives are used for preparing insecticides or active components of the insecticides for killing main biological pests, such as cotton bollworm, diamond back moth, aphid, beet armyworm, armyworm and the like. The oxime ether (ester) derivative with biological activity has the advantages of easy acquirement of raw materials and simple requirements on production equipmen and is simpler for operation. The compounds belongs to aryl oxime ether (ester) compounds with simple and structure, and is possibly widely applied to the pest comprehensive prevention and control. |
