本文合成了九个新型的含磷拟除虫菊酯类化合物和五个新的中间体.研究了亚磷(膦)酸酯的取代基空间位阻对Perkow重排产物中几何异构体的影响,结果表明:取代基位阻增大,产物E/z比值也增大.
Nine new phosphorus-containing pyrethroids and five new intermediates were synthesized in this paper.The effects of the steric hindrance of the substituents on the Perkow rearrangements on the geometrical isomers were studied, The results showed that the steric hindrance of the substituent increased, and the product E / z ratio also increased.
