| titleOfInvention | A novel heterocyclic low-toxicity and high-efficiency pesticide and its preparation method and application |
| abstract | The invention relates to a novel heterocyclic low-toxicity and high-efficiency pesticide and a preparation method and application thereof. The preparation method of the novel heterocyclic low-toxicity and high-efficiency pesticide comprises the following steps: (1) 2-thiohydantoin, benzene After furan-2-formaldehyde, piperidine and absolute ethanol are mixed, heated to reflux temperature and reacted for 2-3 hours, water is added to terminate the reaction, filtered, and the filter residue is washed successively with isopropanol, ethanol, and water, and vacuum-dried to obtain a solid; ( 2) Dissolve the solid obtained in step (1) in methanol, add sodium methoxide and methyl iodide, heat to reflux temperature for 3-5 hours, add water to stop the reaction, filter, wash the filter residue with water, and dry in vacuo to obtain the solid, which is Heterocyclic compounds of formula I. |
