摘要
探讨了S-[(1,2,4-三唑-1-基)芳基(或烷基)甲羰]甲基二硫代磷酸酯衍生物的合成方法,合成了12种含三唑有机磷新化合物,通过红外光谱分析,确定该类化合物P=S振动的吸收频率范围为640~680 cm^(-1),核磁共振氢谱证明,与磷原子相联的基团旋转部分受阻,生物初筛结果表明,部分化合物具有杀菌、除草及植物生长调节活性。
Twelve new triazol organic phosphorus compounds with the general formular (Ⅰ) have been prepared. The structures of these compounds have been confirmed by elemental analysis, and IR, 1H NMR and MS analysis.(R=Me,Et,i-Pr; R =Me3C,C6H5,p-MeOCfiH,i,p-ClC6H4. )The vibrational frequency of the P = S group occurs in the rang 640-680 cm-1. The frequencies of P = S group is primarily dependent upon the electronegativity of the substituent groups.It has been proved by 1H NMR that the substituent groups linked with phosphorus atom spinning are not free because of the steric effect of the substituent groups.The results from the primary biological test show that some of these compounds have the activities of fungicide, herbicide or plant growth regulator.
