From π-Bonded Gallapnictenes to Nucleophilic, Redox-Active Metal-Coordinated Pnictanides.

ABSTRACT: A comprehensive reactivity study of gallapnictenes LGaEGa(Cl)L (E=As, Sb; L=HC[C(Me)N(Ar)]₂ , Ar=Dip=2,6-i-Pr₂ C₆ H₃ ) proved the nucleophilic character of the pnictogen and the electrophilic nature of the Ga atom. Reactions of LGaEGa(Cl)L with imidazolium chloride [IPrH][Cl] yielded {[LGa(Cl)]₂ E^- }{IPrH⁺ } (E=As 1, Sb 2), and those with HCl and MeI gave pnictanes [LGa(Cl)]₂ EH (E=As 5, Sb 6) and L(I)GaE(Me)Ga(Cl)L (E=As 7, Sb 8). Pnictanides 1 and 2 also react with [H(OEt₂ )₂ ][BAr^F ₄ ] (BAr^F ₄ =B(C₆ F₅ )₄ ) to 5 and 6, while reactions with MeI yielded [LGa(Cl)]₂ EMe (E=As 9, Sb 10). Single el
