摘要: 本文测定了标题所示一类化合物的31P的化学位移,并讨论了它与取代基电子性间存在如下的关系
δP=-0.9193σ+3.5891F+66.5385
提出了31P化学位移与此类化合物的除草活性间存在一定的相关性,其关系如下PI50=-0.9025π2+0.9017π-0.5600Es-
0.1620△δP+0.8445I+4.2514
并对此关系的适用性及存在偏差作了初步讨论。

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 approaeh
PI50=-0.9025π2 +0.9017π -0.560Es-
-0.1620ΔδP + 0.8445I+4.2514
n=28, R=0.9231, S=0.3959
Its approximation and discrepancy have been discussed.
