具有Lewis酸碱协同作用的受挫Lewis对(FLP)被认为是最有效的双功能催化体系之一。然而，每个刘易斯组分通常由单个原子组成，因此缺乏协同效应。在这项工作中，簇合物(CFLP)是由Mo-Mo成三角键的MoIV3 Lewis酸性簇合物和H[SbIII3MoIV3MoVI15O55(OH)2py3](1)中的Lewis碱性SbIII配位体组成的。由于MoIV3内部以及MoIV3与SbIII之间更广泛的协同作用，1具有优异的催化性能，为设计合成高效FLP催化剂提供了一种新的思路。
Frustrated Lewis pairs (FLPs) featuring Lewis acid–base synergistic action have been recognized as one of the most powerful bifunctional catalytic systems. Each Lewis component, however, is usually composed of a single atom and hence lacks a cooperative effect. In this work, cluster FLPs (CFLPs) comprised of a triangularly Mo–Mo bonded MoIV3 Lewis acidic cluster component and a Lewis basic SbIII partner in H[SbIII3MoIV3MoVI15O55(OH)2py3] (1) have been developed. The more extensive cooperative actions both within MoIV3 and between MoIV3 and SbIII account for the excellent catalytic performance of 1, providing a new way of thinking for the designed synthesis of highly efficient FLP catalysts.
