Chemistry of the <sup>Me4</sup>PCP pincer ligand has been little explored due to the difficulty of preparation. An efficient procedure utilizing reduction of intermediate iminophosponium salts has been developed. Complexes with iridium exhibit enhanced reactivity with addends such as hydrogen in comparison to complexes containing related ligands with tertiary butyl or isopropyl substituents. The ligand preparation and the reactivity of various irdidium complexes will be described.
