A new methodology has been developed for the P-C bond cleavage of beta-carbonyl phosphonates. The alpha,alpha-disubstituted beta-keto phosphonates and the alpha-carbamoyl phosphonates have been shown to undergo dephosphonylation by reaction of their lithium enolate with LiAlH4, followed by quenching with aqueous H2SO4, affording regioselectively alpha,alpha-disubstituted ketone and alpha-substituted and alpha,alpha-disubstituted secondary amides.
