example 1

[0184] Example 1: Preparation of Compound 2

[0185]

[0186] Take 0.18 g of III-1 and 0.23 g of anhydrous potassium carbonate in a 100 ml reaction flask, add 40 ml of N,N-dimethylformamide (DMF), add 0.45 g of IV-1 under stirring, heat up to 35°C and stir React for 3 hours. After the completion of the TLC monitoring reaction, after desolvation under reduced pressure, pour 50 milliliters of saturated saline into the reaction flask, extract three times with 60 milliliters of ethyl acetate, dry, desolventize, and obtain 0.33 grams of product by column chromatography, namely compound 2.

Abstract

The invention discloses a substituent ether compound which is structurally shown as a general formula (I): the definition of each substituent group refers to an instruction manual. The compound has the broad-spectrum insecticidal activity, is very effective to lepidoptera pests including European corn borers, sugarcane borers, summer fruit tortrix moths, apple budworms, tussock moths, rice leaf rollers, corn borers, tobacco leaf worms, small budworms, cabbage moths, lesser corn worms, cotton leaf worms and the like, particularly has better activity to the cabbage moths and the lesser corn worms and can obtain good effect under the low dosage. The substituent ether compound also has high activity to homoptera pests like aphids and the like. Meanwhile, a part of compound also has good bactericidal activity and can be used for preventing and treating blumeria graminis, cucumber downy mildew, vegetable gray mold and the like.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides and fungicides. In particular, it relates to a substituted ether compound, and the application of using them as insecticides and fungicides in agriculture or other fields. Background technique [0002] Insects are generally known in agriculture to cause not only damage to crop growth, but also damage to buildings and lawns, such as damage caused by soil insects such as termites and grubs. [0003] This damage can result in millions of dollars in loss of associated crops, lawns or buildings. Insecticides and acaricides are useful in controlling insects and mites, but can cause significant damage to crops such as wheat, corn, soybeans, potatoes, and cotton. Insecticides and acaricides that can control insects and mites without damaging crops and have no toxic effects on mammals and other living organisms are needed to protect crops.
