A comprehensive reactivity study of gallapnictenes LGaEGa(Cl)L (E=As, Sb; L=HC[C(Me)N(Ar)] , Ar=Dip=2,6-i-Pr C H ) 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)] E }{IPrH } (E=As 1, Sb 2), and those with HCl and MeI gave pnictanes [LGa(Cl)] 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(OEt ) ][BAr ] (BAr =B(C F ) ) to 5 and 6, while reactions with MeI yielded [LGa(Cl)] EMe (E=As 9, Sb 10). Single electron oxidation reactions of pnictanides 1 and 2 gave the corresponding radicals [LGa(Cl)] E (E=As, Sb).
对镓氮烯LGaEGa(Cl)L(E = As、Sb;L = HC[C(Me)N(Ar)],Ar = Dip = 2,6 - i - Pr₂C₆H₃)进行的全面反应性研究证明了氮族元素的亲核特性以及Ga原子的亲电性质。LGaEGa(Cl)L与氯化咪唑鎓[IPrH][Cl]反应生成{[LGa(Cl)]₂E}{IPrH₂}(E = As 1,Sb 2),与HCl和MeI反应分别生成氮烷[LGa(Cl)]₂EH(E = As 5,Sb 6)和L(I)GaE(Me)Ga(Cl)L(E = As 7,Sb 8)。氮化物1和2也与[H(OEt₂)][BArF₂⁴](BArF₂⁴ = B(C₆F₅)₄)反应生成5和6,而与MeI反应生成[LGa(Cl)]₂EMe(E = As 9,Sb 10)。氮化物1和2的单电子氧化反应生成了相应的自由基[LGa(Cl)]₂E(E = As、Sb)。
