A general method for preparing secondary P-alkenyl and P-alkynyl phosphine oxides, compounds unknown so far, involves the condensation of the vinyl Grignard reagent or lithium acetylide on P-chloroaminophosphines followed by acidic hydrolysis of the corresponding vinyl or ethynylaminophosphines on a solid acid (Amberlyst 15).The few reported chemical properties are mainly related to the strong PH bond activation.Of special interest is the addition of a secondary vinylphosphine oxide derivative on methyl acrylate which occurs at room temperature without any catalyst.
