A long-tethered (P–B–P)-pincer ligand: synthesis, complexation, and application to catalytic dehydrogenation of alkanes

A new long-tethered boron-containing (P–B–P)-pincer ligand has been synthesized. This ligand was introduced to Ir to form (P–B–P)Ir(H)Cl complex. Subsequent reaction with n BuLi led to the formation of dihydride complex (P–B–P)Ir(H) 2 . Both complexes were found to be moderately active for the catalytic dehydrogenation of alkanes.
