Abstract

A new PC(sp³)P ligand N,N′-bis(diphenylphosphino)dipyrromethane [PCH₂P] (1) was prepared and its iron, cobalt and nickel chemistry was explored. Two pincer-type complexes [PCHP]Fe(H)(PMe₃)₂ (2) and [PCHP]Co(PMe₃)₂ (4) were synthesized in the reaction of 1 with Fe(PMe₃)₄ and Co(Me)(PMe₃)₄. 1 reacted with Co(PMe₃)₄ and Ni(PMe₃)₄ to afford Co(0) and Ni(0) complexes [PCH₂P]Co(PMe₃)₂ (3) and [PCH₂P]Ni(PMe₃)₂ (5). The structures of complexes 2–5 were determined by X-ray diffraction.
