| Abstract: | In this article, We have measured the 31P chemical shifts of the title compounds and discussed the relationship of their chemical shift-electronic effect.It is suggested that a correlation between 31P chemical shifts of various O-ethyl O-aryl N-isopropyl aminothionophosphates and their herbicidal activities can be set up as shown in the following empirical approaehPI50=-0.9025π2 +0.9017π -0.560Es--0.1620ΔδP + 0.8445I+4.2514n=28, R=0.9231, S=0.3959Its approximation and discrepancy have been discussed. |
