摘要
采用相转移双催化技术 ,以 79%～ 95 %的收率合成了 9种 O-烯丙基 - O-芳基 - O-甲基不对称硫逐磷酸酯 ( ) ;并通过 的重排反应合成了烯丙硫基不对称硫赶磷酸酯 ,重排前后化合物的结构均得到了元素分析、IR、1H NMR和 3 1P NMR的证实 ;
Nine new O aryl O methyl O allyl thionophosphates were synthesized with PTC in 79%~95% yields ;and its rearrangement effect was studied. The chemical structures were comfirmed by elemental analysis, IR and NMR spectroscopy. Mortality of aphis from the compounds Ⅲ 1~9 and Ⅳ 1~9 was tested in dosage of 250 mg/L.
