近年来, 利用稀土金属作为路易斯酸, 与主族路易斯碱组合的路易斯酸碱对得到了开发. 这类酸碱对组合通过路易斯酸与路易斯碱协同作用, 从而实现底物的活化, 展示了与传统稀土金属配合物不同的活化模式. 其可以与氢气反应, 断裂非极性的氢-氢键; 也能够与羰基类、重氮类及叠氮类等不饱和小分子反应, 得到一系列结构独特的稀土金属配合物. 同时这类路易斯酸碱对也可以用于催化极性烯烃聚合反应、二氧化碳硅氢化还原反应中, 展现出优异的催化性能. 综述了上述研究结果, 并对该领域的发展趋势和前景进行了展望.

Rare-earth (RE) metal-base Lewis pairs comprised of Lewis acidic RE metals and main group Lewis bases have been developed recently. Distinct from traditional reaction pathway mediated by RE metal complexes, it’s the synergistic effect between Lewis acidic RE metal center and Lewis basic center that enables the activation of incoming substrates. This kind of extraordinary Lewis pairs can split the non-polar H-H bond, as well as react with carbonyl compounds, diazo compounds, azide compounds, etc., leading to a series of unique and intriguing RE metal complexes. Meanwhile, these Lewis pairs are also applied as catalysts for polymerization of conjugated polar alkenes and hydrosilylation of carbon dioxide with excellent results. Researches mentioned above are reviewed in this paper, and new prospects for the future development of RE based Lewis pairs are put forward.
