Synthesis, Reactivity and Coordination Chemistry of Group 9 PBP Boryl Pincer Complexes: [(PBP)M(PMe₃)_n] (M = Co, Rh, Ir; n = 1, 2).

ABSTRACT: The unsymmetrical diborane(4) derivative [(d(CH₂P(iPr)₂)abB)-Bpin] (1) proved to be a versatile PBP boryl pincer ligand precursor for Co(I) (2a, 4a), Rh(I) (2-3b) and Ir(I/III) (2-3c, 5-6c) complexes, in particular of the types [(d(CH₂P(iPr)₂)abB)M(PMe₃)₂] (2a-c) and [(d(CH₂P(iPr)₂)abB)M-PMe₃] (2b-c). Whilst similar complexes have been obtained before, for the first time, the coordination chemistry of a homologous series of PBP pincer complexes, in particular the interconversion of the five- and four-coordinate complexes 2a-c/3a-c, was studied in detail.
