Abstract

Abstract The 31P NMR chemical shifts of a series of substituted O-phenyl diethyl phosphinates and dihexyl phosphates were determined. The results showed that 31P NMR chemical shifts of aryl diethylphosphinates moved downfield as the electron withdrawing ability of the nuclear substituent enhanced. The regression analyses involving 31P NMR chemical shifts and Hammett σ substituent constants provided fair correlation coefficient. ...
