Hypophosphite solutions in carboxylic acids
Abstract
Hypophosphite salts are very soluble in carboxylic acid solvents and a study of these solutions by various physical and spectroscopic methods (i.r., and 1H and 31P n.m.r.) shows that strong, but not very strong, hydrogen bonding is the principal solute–solvent interaction of the anion. An unusual feature of the solutions is the sensitivity of JHP(H2PO2–) to the solvent medium and it is suggested that this parameter is a guide to the location of the proton of the hydrogen bond.
