Abstract
The conformations of diethyl 2-hydroxypropylphosphonate in CDCl3 were studi ed by means of NMR spectroscopy. This compound forms species in which inter molecular hydrogen bonding prevails in concentrated solutions whereas intra molecular bonds are predominant in dilute solutions. Usually both types of species exist in dynamic equilibrium and the formation of a certain hydroge n bond determines which of the conformers (trans or gauche) is predominant in a given solution.
