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 8 has been synthesized. Complexation of 8 with [Ir(coe) Cl] (coe = cyclooctene) resulted in (P-B-P)(hydrido)chloroiridium complex (P-B-P)Ir(H)Cl 9. Subsequent reaction with BuLi led to the formation of dihydride complex (P-B-P)Ir(H) 10. Both...

Description
Summary:A new long-tethered boron-containing (P-B-P)-pincer ligand 8 has been synthesized. Complexation of 8 with [Ir(coe) Cl] (coe = cyclooctene) resulted in (P-B-P)(hydrido)chloroiridium complex (P-B-P)Ir(H)Cl 9. Subsequent reaction with BuLi led to the formation of dihydride complex (P-B-P)Ir(H) 10. Both complexes were found to be moderately active for the catalytic dehydrogenation of alkanes.
