A coupling of bromoalkynes with secondaryphosphineoxides was developed for the synthesis of alkynylphosphine oxides. This transformation was accomplished under additive-free conditions in acetic anhydride (Ac2O). The reaction could be carried out under mild conditions, and a wide range of secondaryphosphineoxides were obtained in good yields.
