Abstract Palladium-catalyzed Michaelis-Arbuzov reaction of allyl acetates with trialkyl phosphites affords dialkyl allylphosphonates. Diethyl 2-oxoethylphosphonate is efficiently prepared by ozonization of diethyl allylphosphonate.

The enantioselective Pd-catalyzed allylation of diaryl-substituted allylic carbonates and diphenylphosphineoxide was investigated. This method gave allylic diphenylphosphineoxides in yields up to 95 % with 97 % ee. Pd-catalyzed allylation of (E)-methyl allyl carbonates with diisopropyl phosphonate was also examined.
