合成了一种含Al-B键和扭曲Al、B平面的四有机铝硼烷（3），并对其结构进行了表征。利用紫外-可见吸收光谱、电化学测量和密度泛函理论计算研究了3。研究了3对DMSO和CO的反应性，以证明其脱氧能力。在DFT计算结果的基础上，提出了详细的反应机理，强调了13族元素Al和B的独特刘易斯酸性在3.
A tetraorganyl-alumaborane (3) that contains an Al–B bond and twisted Al and B planes was synthesized and structurally characterized. UV–vis absorption spectroscopy, electrochemical measurement, and DFT calculations were employed to reveal the electronic properties of3. The reactivity of3toward DMSO and CO was studied to demonstrate its deoxygenating abilities. On the basis of the results of the DFT calculations, a detailed reaction mechanism was developed, which highlighted the important role of the distinct Lewis acidity of the group-13 elements Al and B in3.
