Sb2R4 类型的二丁烷与三烷基丙烷和镓烷 R‘3M 以 1:2 化学计量进行反应，生成 8 种 [Sb2R4][MR‘3]2 类型的双加合物 (R = Me, R‘ = t-Bu, M = Al 1, Ga 2; R = Et, M = Al, R‘ = Me 3, Et 4, t-Bu 5; M = Ga, R‘ = Me 6、Et 7、t-Bu 8)，通过多核 NMR 研究和元素分析对其进行了表征。此外，1、2、5和8是第一个具有结构特征的中性主族路易斯酸-二苯乙烯双加合物。 1−8 在溶液中不稳定，无法形成 [R2SbMR‘2]x 类型的杂环。 [Me2SbGa(t-Bu)2]3 (9) 和 [Et2SbGa(t-Bu)2]2 (10) 已被分离出来，并通过单晶 X 射线衍射确定了它们的固态结构。
Reactions between distibanes of the type Sb2R4 and trialkylalanes and -gallanes R‘3M in 1:2 stoichiometry yield eight bisadducts of the type [Sb2R4][MR‘3]2 (R = Me, R‘ = t-Bu, M = Al 1, Ga 2; R = Et, M = Al, R‘ = Me 3, Et 4, t-Bu 5; M = Ga, R‘ = Me 6, Et 7, t-Bu 8), which were characterized by multinuclear NMR studies and elemental analysis. In addition, 1, 2, 5, and 8 are the first structurally characterized neutral main group Lewis acid−distibane bisadducts. 1−8 are unstable in solution toward the formation of heterocycles of the type [R2SbMR‘2]x. [Me2SbGa(t-Bu)2]3 (9) and [Et2SbGa(t-Bu)2]2 (10) have been isolated and their solid state structures determined by single-crystal X-ray diffraction.
