Phosphinates orhypophosphites are a class ofphosphorus compounds conceptually based on the structure ofhypophosphorous acid.IUPAC prefers the term phosphinate in all cases, however in practice hypophosphite is usually used to describe inorganic species (e.g.sodium hypophosphite), while phosphinate typically refers toorganophosphorus species.

. The salts are prepared by heating white phosphorus in warm aqueous alkali e.g. Ca(OH)2:[1]
Hypophosphites arereducing agents:[1]
Hypophosphites are used inelectroless nickel plating as the reducing agent to deposit for example Ni metal from Ni salts.[1] The hypophosphite ion is thermodynamically unstable, anddisproportionates on heating tophosphine andphosphatesalts:
