Synthesis of a Gallaarsene {HC[C(Me)N-2,6-i-Pr2-C6H3]2}GaAsCp* Containing a Ga═As Double Bond

Cp*AsCl2 (Cp* = C5Me5) reacts with one equivalent of LGa (L = HC[C(Me)N(2,6- i-Pr2C6H3)]2) with formation of L(Cl)GaAs(Cl)Cp* 1, whereas the reaction with two equivalents of LGa yielded gallaarsene LGaAsCp* 2 containing a Ga═As double bond and (η1-Ga(Cp*)L(η2-GaL)(μ-As3) 3. Compounds 2 and 3 were structurally characterized by single crystal X-ray diffraction, and the π-bonding contribution in 2 was analyzed by temperature-dependent 1H NMR spectroscopy (9.65 kcal mol-1) and by quantum mechanical computation.
