Synthesis of 3-Oxoalkylphosphonates via the Conjugate Addition of Acylcuprates to Diethyl Vinylphosphonate. -Acylcuprates, generated in situ from dialkylcyanocuprates (I) and carbon monoxide, are added to vinylphosphonate (III) to give, after hydrolysis, phosphonates (IV) in good yields. Phosphonat
