Abstract: 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, 1HNMR 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 1HNMR 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.
