摘要
作为一种新型的非金属有机催化剂,空间受阻型路易斯酸碱对由于具有的独特化学反应性,近年来在有机小分子活化和催化加氢领域的研究非常活跃。本文总结了近年来国外发表的有关空间受阻型路易斯酸碱对的研究报道,从其结构特征、有机小分子的活化、H2活化机理的探讨及在催化领域应用的研究成果4个方面进行了详细的归纳整理。空间受阻型路易斯酸碱对对有机小分子的活化作用来源于其"分子间静电相互作用力"。这个在有机化学中早已熟知的概念却在2006年才被发现可活化有机小分子,并在之后受到广泛的关注。空间受阻型路易斯酸碱对化学的发展也扩展了有机化学反应研究的范畴,继续深入研究这种"分子间静电相互作用力"在其他未知领域的应用必将带来更大的发现。然而目前国内从事相关领域研究的报道很少,因此希望本文能够引起国内更多科研工作者对这个新兴领域产生研究兴趣。
Recently, frustrated Lewis pairs （FLPs） with unique chemical properties were found to exhibit high activity in catalytic hydrogenation and activation of small molecules. FLPs are now considered as a new prospective type of transition metal free catalysts and this area of chemistry is currently under intense development. This review summarizes the data of the recent achievements in this field. Different aspects concerning the FLPs＇ nature, their capability to activate small molecules, possible mechanisms of the dihydrogen activation, along with the known practical applications of FLPs in catalysis are discussed in details. While the driving forces responsible for the reactivity of FLPs in respect to small molecules seem to be rather evident and, actually, present classical electrostatic intermolecular interactions, prior to the first reports on FLPs this brilliantly simple concept has never been utilized in the catalyst design. Since the pioneering work on FLPs in 2006, it is the native elegance of the approach which defines the general productivity of the investigations in this prospective direction. Unfortunately, till now the studies on the FLPs＇ chemistry are comparatively few in China. We hope that this contribution could drive more attention of Chinese researchers to this interesting and potent area of modern chemistry.
