                                    A facile method for the synthesis of trisubstituted allenynes has been developed. The process involves phosphane-mediated deoxygenation of 2,4-pentadiyn-1-ol derivatives. A variety of propargyl alcohols can be transformed into allenynes in moderate to good yields under mild reaction conditions.
