Double E─H Bond Activation of Ammonia and Water by Cyclic Gallaphosphene L(OCP)GaPGaL.

ABSTRACT: Cyclic gallaphosphene L(PCO)GaPGaL 1 (L = HC[C(Me)NAr]₂; Ar = 2,6-i-Pr₂-C₆H₃) selectively reacts with NH₃ and H₂O at ambient temperature with twofold N─H and O─H bond activation and formation of compounds LGa(μ-PH)(μ-NHC(O)PH)GaL 2 and LGa(μ-PH)(μ-OC(O)PH)GaL 3. Both nucleophilic P atoms of 1 are protonated in these reactions, while the electrophilic carbon atom of the bridging PCO unit binds to the remaining NH group / O atom. The formation of heterocycles 2 and 3, which were characterized by heteronuclear NMR (¹H, ¹³C{¹H}, ³¹P{¹H}) and IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction (sc-XRD), is only possible due to a beneficial interplay betw
