Give and take: A cationic N-heterocyclic carbene (NHC)-phosphenium adduct is prepared (see picture; orange = P, lilac = N, gray = C, white = H). On reaction with [Pt(PPh3)3] it splits into its constituent parts, delivering an NHC ligand (a strong σ donor) and a phosphenium ligand (a π acceptor) from one reagent. These first platinum phosphenium complexes are characterized by short Pt-P bonds and large Pt-P coupling constants.
