| Abstract: | Clothianidin is one of new neonicotinoids with good efficacy, broad spectrum and low toxicity for the non-targeted species. The synthesis of clothianidin was introduced in this paper. And one of the methods was researched in detailed in this paper. It started from nitroguanidine and 2,3-dichloropropene, and resolve the material named N-(1- ((2-chlorothiazol-5-propyl-1,3,5-triazinan-2-ylidene) nitamide into clothianidin. The method was suitable for industrial preparation by its many advantages such as effect... |
