Summary: This article discusses the potential of metal-organic frameworks (MOFs) in heterogeneous catalysis as frustrated Lewis acid-base pairs (FLPs) or bifunctional acid-base solid catalysts for activating molecular hydrogen. Specifically, it focuses on the use of MOFs as Lewis acid and Lewis base catalysts, and the efforts to heterogenize boron and amine in MOFs to mimic molecular FLP systems. The article highlights the catalytic hydrogenation capabilities of UiO-66 and MIL-101 MOFs and their significance in selectively hydrogenating polar double X=Y bonds.

Summary: This paper describes the development of cooperative and synergistic catalyst systems of heterogeneous Rh-Pt bimetallic nanoparticle catalysts, Rh-Pt/DMPSi-Al2O3, and Sc(OTf)(3) in the liquid phase for the hydrogenation of arenes under very mild conditions. The cooperative activation achieved significant rate acceleration and successful hydrogenation of challenging substrates with strong electron-donating groups and sterically hindered substituents was demonstrated.

Summary: The development and application of new organoboron reagents as Lewis acids have expanded over the past 20 years. This review focuses on the recent uses of BPh3 as a metal-free catalyst in various organic transformations. The catalytic applications include polymer synthesis, hydrogen cleavage, hydrogenation, N-methylation, C-methylation, cycloaddition, and insertion reactions. This mini-review highlights the underexplored potential of commercially available BPh3 in metal-free catalysis.

Summary: The newly synthesized compound iPr(3)SnNTf(2) exhibits stronger Lewis acid properties compared to previously studied compounds, enabling faster hydrogen activation and catalytic hydrolysis of ester bonds. The reaction outcome is influenced by the steric and electronic properties of the substrate, with computational studies revealing differences in the reaction mechanisms between different ester substrates.

Summary: Precisely controlling the structure and spatial distance between Lewis acid and Lewis base sites in a porous system is essential for constructing efficient solid frustrated Lewis pair (FLP) catalysts. In this study, FLP sites were constructed in a polyoxometalate (POM)-based metal-organic framework (MOF) by introducing coordination-defect metal nodes (Lewis acid) and surface-basic POM with abundant oxygen (Lewis base). The resulting FLP catalyst exhibited high hydrogenation activity, with 55 and 2.7 times higher activity compared to defect-free POM-based MOF and defective MOF without POM, respectively. This work offers a new approach for the precise design of multi-site catalysts for specific substrate activation and synergistic catalysis.

Summary: The research investigates the Lewis acidities of carbon compared to B(C6F5)(3) in combination with dioxane for metal-free catalysis of heterolytic H-2 splitting and hydrogenation of carbonyl compounds, finding that the reaction is controlled by frontier molecular orbital interactions and electrophilic substitutions on the carbonyl carbon to reduce steric effects. Stronger orbital interactions and reduced steric effects can lower the barrier of the H-2 splitting.

Summary: In this study, a strategy for integrating molecular chiral frustrated Lewis pair (CFLP) with porous metal-organic framework (MOF) was proposed and the catalyst CFLP@MOF was successfully constructed, which enables heterogeneous asymmetric hydrogenation. The developed CFLP@MOF catalyst exhibits high activity/enantio-selectivity and excellent recyclability/regenerability, providing a new avenue for the design and preparation of advanced catalysts for asymmetric catalysis.

Summary: This article provides a review of the chemistry of frustrated Lewis pair (FLP) in the activation of small molecules, hydrogenation of CO2, and unsaturated organic species. Experimental works and electronic structure theory calculations are used to gain mechanistic insights into the reactivity of FLPs. The findings can guide the design of more efficient FLP catalysts for hydrogen activation.

Summary: The application of heterogeneous catalysts in continuous-flow enantioselective hydroacylation reactions was studied. Catalysts were prepared by mixing supports and rhodium complexes, and showed excellent activity and enantioselectivity. Under optimized conditions, the catalysts exhibited high turnover numbers and could be applied to various substrates. Furthermore, sequential-flow reactions with other heterogeneous catalysts were demonstrated for the synthesis of biologically active molecules and functional materials.
