(X=Cl, Br, I; Cp*=C5Me5) to group 13 diyls LM (M=Al, Ga, In; L=HC[C(Me)N (Dip)]2, Dip=2,6‐iPr2C6H3) yields elemental antimony (M=Al) or the corresponding stibanylgallanes [L(X)Ga]Sb(X)Cp* (X=Br 1, I 2) and ‐indanes [L(X)In]Sb(X)Cp* (X=Cl 5, Br 6, I 7). 1 and 2 react with a second equivalent of LGa to eliminate decamethyl‐1,1’‐dihydrofulvalene (Cp*2) and form stibanyl radicals [L(X)Ga]2Sb. (X=Br 3, I 4)
将Cp * SbX 2(X = Cl,Br,I; Cp * = C 5 Me 5)氧化加成到第13组二基LM(M = Al,Ga,In; L = HC [C(Me)N(Dip)) ] 2,Dip = 2,6 - i Pr 2 C 6 H 3)产生元素锑(M = Al)或相应的stibanylgallanes [L(X)Ga] Sb(X)Cp *(X = Br 1,I 2)和茚满[L(X)In] Sb(X)Cp *(X = Cl 5,Br 6,I 7)。1和2与第二当量的LGa反应,消除十甲基-1,1'-二氢富瓦烯(Cp * 2)并形成stibanyl基团[L(X)Ga] 2锑。(X = Br 3,I 4),而5和6与LIn的类似反应通过消除1,2,3,4选择性产生stibanes [L(X)In] 2 SbH(X = Cl 8,Br 9) -四甲基富勒烯。提议通过形成[L(X)M] 2 SbCp
