A coordinatively unsaturated dicationic phosphorus compound has been synthesized and characterized (see structure; P pink, N blue, C gray). DFT calculations revealed that the polycation should show superior Lewis acid and σ-donor properties to the corresponding bis(dimethylamino)phosphenium cations. Preliminary investigations with PMe3 confirmed unusual reactivity patterns for the dication.
