phosphite and ethyl bromoacetate produces a phosphonate suitable for use in the Horner-Wadsworth-Emmons reaction.

Reduction/deoxygenation of hydroperoxides to the alcohols can also be effected using triethyl phosphite. This approach can be utilized for carbonyl ?-hydroxylation by reacting the enolate with oxygen, producing an ?-hydroperoxide which can be reduced by triethyl phosphite to the alcohol.
