摘要: We synthesized a PBP pincer ligand precursor 2 and demonstrated its complexation with iridium(I) to afford the coordinatively unsaturated [PBP](hydrido)chloroiridium complex 3 via B−H oxidative addition. The reaction of carbon monoxide produced [PBP](hydrido)chloro(carbonyl)iridium 7. longer Ir−Cl bond length 7 than that 8 revealed stronger σ-donor ability PCP. Complex was also converted [PBP](ethylene)iridium(I) 9 by LiTMP under an ethylene atmosphere.
