¹³C NMR studies of some dialkyl α‐anilinobenzylphosphonates and dialkyl α‐anilino‐(2‐hydroxybenzyl)phosphonates

Abstract

Abstract The 13 C NMR spectra of a series of dialkyl α‐anilinobenzylphosphonates and dialkyl α‐anilino‐(2‐hydroxybenzyl)phosphonates were measured. The assignment of the spectra was performed using a combination of 31 P‐ 13 C and 13 C‐ 1 H coupling constants and substituent‐induced chemical shifts. Long‐range phosphorus‐carbon couplings up to five bonds were observed.
