The first goal of this work was to explore the feasibility of diaryl-mercury species as the synthetic precursors of triaryl-gallium species GaAr*₃ (where Ar*= pH, 4; Ar*= 3,5-difluorophenyl, 5; and Ar*= 3,5-trifluoromethylphenyl, 6). Expecting that 4–6 behave as Lewis acids of different strength, the second purpose was to use them for the synthesis of either rollover or classic cyclometallated Ga compounds. Three analogous diaryl-mercury HgAr*₂ species, 1–3, were successfully synthesized. The structures of compounds 2 and 3 were confirmed by gas chromatography - mass spectrometry experiments. Additionally, compound 3 was analyzed through X-ray diffraction; in the crystal structure obtained, π-stacking interactions were observed. The only Ga compound synthesized was GaPh₃, 4, because the presence of fluorine-containing groups in meta-position caused sublimation of the respective mercury diaryl compounds, impeding their reaction with gallium. The attempts toward the synthesis of the rollover or classic cyclometallated compounds in the reaction of 4 with bipyridine-, pyrazole- or benzo-imidazole- type ligands have failed. On the other hand, under the experimental conditions applied, water traces favored formation of the solid aryl-Ga cluster containing twelve Ga atoms [Ga₁₂], whereas the above-mentioned ligands were quantitatively recovered in the solution. The identity of aryl-gallium cluster was confirmed by electrospray ionization - high resolution mass spectrometry. Although Ga cluster was not expected, it is considered an important finding of this work, owing to the variety of possible applications and still limited data available on the synthesis and structural characterization of such compounds.

_{这项工作的首要目标是探索二芳基汞物种作为三芳基镓物种 GaAr* 3}的合成前体的可行性（其中 Ar*= pH, 4；Ar*= 3,5-二氟苯基，5；Ar *= 3,5-三氟甲基苯基，6)。预计 4-6 会表现出不同强度的路易斯酸，第二个目的是使用它们来合成翻转或经典的环金属化 Ga 化合物。成功合成了三种类似的二芳基汞 HgAr* ₂物质 1-3。通过气相色谱-质谱实验证实了化合物2和3的结构。另外，通过X射线衍射分析了化合物3；在获得的晶体结构中，观察到π堆积相互作用。唯一合成的 Ga 化合物是 GaPh_如图3 、图4所示，由于间位含氟基团的存在导致各自的汞二芳基化合物升华，阻碍了它们与镓的反应。在4与联吡啶、吡唑或苯并咪唑型配体的反应中合成翻转或经典环金属化化合物的尝试已经失败。另一方面，在所应用的实验条件下，痕量水有利于含有12个Ga原子[Ga ₁₂ ]的固体芳基-Ga簇的形成，而上述配体在溶液中定量回收。通过电喷雾电离证实了芳基镓簇的身份 -高分辨率质谱分析。尽管 Ga 簇不是预期的，但由于可能的应用多种多样，而且此类化合物的合成和结构表征的可用数据仍然有限，因此它被认为是这项工作的重要发现。
