  使用氨基三酚镓化合物催化形成环状碳酸酯及其铝同类物的比较：一项联合实验和计算研究

  摘要：

  这项工作报告了使用氨基三酚镓化合物作为由环氧化物和 CO 2合成环状碳酸酯的催化剂. 结果表明它们具有高活性，并且比相应的铝同系物活性更高。该催化剂体系适用于低温和高温下的广泛底物范围，包括末端环氧化物、内部环氧化物、多重环氧化物和完全氘化环氧化物。应用低催化剂负载量可以获得 344,000 的 TON，突出了它们的稳定性。DFT 研究证实，与铝同系物相比，镓催化剂具有较低的能量分布。使用 Gutmann-Beckett 方法测量镓和氨基三酚铝化合物的路易斯酸度提供了实验证据，证明镓化合物比其铝同系物更具路易斯酸性。最后，

  Gallium alkoxides: Synthesis and properties

  摘要：

  Compounds Ga(OR)(3) (R = Me, Et, Pr-i, Bu-n, C2H4OMe) were synthesized by exchange reactions between gallium chloride and alkali metal alkoxides, the reetherefication of Ga(OPri)(3) and Ga(OC2H4OMe)(3) by other ROH (R = Me, Et), and anodic dissolution of metallic gallium in the presence of a electroconductive additive (LiCl, Bu4NBr). When solid GaCl3 is introduced into an alcoholic solution of NaOEt, stable soluble gallium oxoalkoxyhalides are formed. The same reaction with a GaCl3 solution in toluene or electrochemical synthesis produces nonvolatile Ga(OEt)(3) samples, which have the polymer zigzag configuration [Ga(OR)(4/2)(OR)](infinity). Mass spectrometry shows that only Ga(OPri)(3) and freshly prepared X-ray amorphous Ga(OEt)(3) samples (produced by reetherefication) are transferred to the gas phase. The spectra of the latter contain ions generated by penta-and hexanuclear oxoalkoxide molecules, along with fragments of orthospecies [Ga(OEt)(3)](2-4). IR spectra are described for all compounds synthesized.

The results show that they are highly active, and more so than the corresponding aluminium congeners. The catalyst system is applicable at low and elevated temperatures across a wide substrate scope including terminal, internal, multiple and fully deuterated epoxides. Applying low catalyst
