摘要

Abstract The 31P NMR chemical shifts of a series of meta-and para-substituted phenyl diphenylphosphinates, Ph2P (O) OC6H4-X. have been determined. The δ 31P values exhibit an increasing downfield trend as the electron-withdrawing properties of the substituent X become greater and a reasonable correlation between δ 31P and Hammett– Taft substituent constants is obtained. This trend is opposite to that exhibited in several ...
