Versuchsvorschrift

Palladium on carbon (10%, 100 mg) was added to a solution of diethyl 2-(benzyloxy)ethoxymethylphosphonate prepared in this manner (0.9 g,2.8 mmol) and cyclohexene (2.0 ml, 20 mmol) in 20 ml ethanol under a nitrogen atmosphere. The resulting slurry was heated to reflux overnight. The catalyst was filtered off and the solution concentrated under vacuum to yield 0.5 g of diethyl 2-hydroxyethoxymethylphosphonate.
