Description

technical field [0000] The present invention relates to a class of compounds and applications thereof, specifically 5-[2-(benzimino)thiazol-4-yl]furan phenol ether, i.e. 4-(7-hydroxyl / alkoxyl-2,2-dimethyl -2,3-Dihydrobenzofuran-5-yl)-2-benziminothiazole and its use for the preparation of insecticides. Background technique [0000] Furanol (chemical name 2,2-dimethyl-2,3-dihydrobenzofuranphenol) is an important intermediate in the production of large-tonnage carbamate pesticides such as carbofuran, haoanwei and carbofuran. Carbamate pesticides have high activity and are widely used, but they are more toxic. Therefore, it is necessary to develop alternative products with lower toxicity and better activity to meet the market demand. As we all know, it takes 8 to 10 years to develop a new pesticide variety. In addition, there are many data and projects required for the registration of new pesticide varieties, and the cost is hundreds of millions of dollars. There are already i...
