L=HC[C(Me)N(2,6‐iPr2C6H3)]2} reacts with SbX3 to form the Ga‐substituted distibenes [(LGaX)2Sb2] (X=NMeEt 1, Cl 2). Upon heating, 2 reacts to the bicyclo[1.1.0]butane analogue [(LGaCl)2(μ,η1:1‐Sb4)] 3 containing a [Sb4]2− dianion. Moreover, 2 reacts with Li amides LiNR2 in salt elimination reactions that form the corresponding amido‐substituted compounds 1 and [(LGaNMe2)2Sb2] 4, whereas reactions of 4 and
单价没食子二烷基LGa L = HC [C(Me)N(2,6 - i Pr 2 C 6 H 3)] 2 }与SbX 3反应形成Ga取代的二萜[[LGaX)2 Sb 2 ](X = NMeEt 1,Cl 2)。加热后,2与含有[Sb 4 ] 2-二价阴离子的双环[1.1.0]丁烷类似物[(LGaCl)2(μ,η1 :1 -Sb 4)] 3反应。此外,2与锂酰胺LiNR 2反应在形成相应的酰胺基取代的化合物1和[(LGaNMe 2)2 Sb 2 ] 4的盐消除反应中,而4和[(LGaNMe 2)2(μ,η1 :1 ‐Sb 4)] 5与两当量的GaCl 3分别形成2和3。1,2和3进行了表征1 H和13C NMR光谱,元素分析和单晶X射线衍射。另外,通过量子化学计算分析了它们的键合情况。
