Iridium Complexes of a Bis(<i>N</i>-pyrrolyl)boryl/Bis(phosphine) PBP Pincer Ligand.

ABSTRACT: This work reports the synthesis of a bis(pyrrolylphosphino)phenyl borane (PBP)Ph (2) and its incorporation of Ir by metal insertion into B-Ph to afford the dipyrrolylboryl/bis(phosphine) pincer complex (PBP)Ir(Ph)Cl (3). Hydrogenolysis of 3 afforded (PBP)Ir(H)Cl (4). Compound 4 was converted into (PBP)IrCl₂ (5a) via reaction with N-chlorosuccinimide, and exposure of 5a to CO produced (PBP)IrCl₂(CO) (6a). Compounds 5a and 6a were converted into their analogs (PBP)IrI₂ (5b) and (PBP)IrI₂(CO) (6b) via metathesis with Me₃SiI, respectively. Treatment of either 3 or 4 with Li[HAl(O^tBu)₃] under H₂ resulted
