从现有的双双二氢化allane加合物制备了一系列双二氢化allane（4）的卡宾加合物，随后交换它们的卤化物，建立了从二氢化allane加合物进行碱和卤化物交换反应的可行性。此外，一系列的二镓物种处理过渡金属刘易斯碱，导致交替氧化加成产物，物种与单配位Ga+配体，和一个不寻常的ditopic金属只有刘易斯对（MOLP）。这些结果强调了具有刘易斯碱的卤代镓烷物种的多样和不可预测的化学性质。
A range of double carbene adducts of digallanes(4) are prepared from an existing double digallane adduct, and their halides are subsequently exchanged, establishing the feasibility of both base and halide-exchange reactions from digallane adducts. Furthermore, a range of digallium species are treated with transition-metal Lewis bases, leading alternatively to oxidative addition products, species with monocoordinate Ga+ ligands, and an unusual ditopic metal-only Lewis pair (MOLP). These results underline the manifold and unpredictable chemistry of halogallane species with Lewis bases.
