Versuchsvorschrift

Diethyl 1,3-dimethyl-5-oxocyclohexanephosphonate (B.pt. 120°/0.1 mm) was prepared by the base catalysed addition of diethylphosphite to 3,5-dimethyl-2-cyclohexen-1-one. Hydrolysis of the ester in concentrated HCl gave 1,3-dimethyl-5-oxocyclohexanephosphonic acid as a viscous oil.
