Bis(1-bora-4-phosphorinane) ring closure at Cp*M (M = Fe, Co) complexes

Abstract

Bis(1-bora-4-phosphorinane) metal complexes have been synthesized using a Cp*M-protecting (M = Fe^IICl, Co^I, Cp* = C₅Me₅⁻) strategy and structurally authenticated by NMR spectroscopy and single crystal X-ray diffraction. Synthesis of these scaffolds is highly sensitive to the identity of vinylphosphine precursor. This approach provides a new method for the generation of saturated P,B-containing main-group ring systems.
