Synthesis of Pincer Iridium Complexes Bearing a Boron Atom and ^<i>i</i>Pr-Substituted Phosphorus Atoms: Application to Catalytic Transfer Dehydrogenation of Alkanes

An ^<i>i</i>Pr-substituted PBP-pincer ligand was synthesized and introduced to iridium metal to give ^<i>i</i>Pr-(PBP)­Ir­(H)Cl and ^<i>i</i>Pr-(PBP)­Ir­(C₂H₄) complexes. Both of these complexes were found to be moderately active for the catalytic transfer dehydrogenation of cyclooctane
