N₂Cleavage on d⁴/d⁴Molybdenum Centers and Its Further Conversion into Iminophosphorane under Mild Conditions

Abstract

The synthesis of N-containing organophosphine compounds using N₂ as the nitrogen source under mild conditions has attracted much attention. Herein, the conversion of N₂ into iminophosphorane was reported. By visible light irradiation, N₂ was split on a Mo^II complex bearing a PNCNP ligand, directly forming the Mo^V nitride. After the N-P bond formation on the terminal nitride, the N atom from N₂ was ultimately transferred into iminophosphorane. Key intermediates were characterized.
