Summary: Transition metal species readily capture and react with CO, while main group CO adducts and their subsequent reactivity have been less studied. This review focuses on the application of Frustrated Lewis Pairs (FLPs) to develop main group chemistry of CO, illustrating the ability to capture CO and subsequent reduction reactions. These developments suggest that FLPs provide an alternative strategy to enhance the reactivity of CO, promising future advances in homogeneous CO chemistry.

Summary: The frustrated Lewis pair (FLP) concept has been successfully applied to heterogeneous catalysis by using a supramolecular system involving deprotonated zeolite framework oxygens and confined carbocations in methanol-to-olefin (MTO) reactions. This FLP showed the capability of H-2 heterolysis and alkane dehydrogenation, which was confirmed by catalytic experiments using GC-MS inside FLP-containing chabazite zeolites.

Summary: The versatile chemistry of boronic acid and boronate ester containing polymers has led to key applications in drug delivery, chemical sensing, and dynamic materials. In this paper, a novel fluorinated borinate ester copolymer was synthesized, which, when combined with a suitable Lewis basic copolymer, generated polymeric FLP networks capable of responsive gelation. The physical parameters and nature of the crosslinks of the gels prepared from different crosslinkers were probed by rheology, demonstrating strong elastic behavior and covalently crosslinked materials.

Summary: A frustrated Lewis pair composed of dititanoxycarbene and B(C6F5)(3) successfully cleaved dihydrogen under ambient conditions, resulting in the formation of a zwitterionic formate and a hydrido borate. This method demonstrates the capability of specific compounds to act as unique Lewis pairs for the activation of dihydrogen.

Summary: By utilizing benzyl alcohol as a co-modulator, carbodicarbene is transformed into a Frustrated Lewis Pair-like reactivity, showing enhanced catalytic activity in various chemical reactions. This unique catalytic reactivity differs significantly from conventional NHC carbenes, demonstrating a new approach in diversifying FLP reactivity with the use of co-modulators.

Summary: The hydrocracking process of aromatic rings in the petrochemical industry has been studied using density functional theory. It is found that the Lewis acid site composed of a single extraframework-Al3+ atom is the most stable mononuclear extraframework aluminum species. Molecular dynamics simulations show that this site is the most efficient catalytic center for hydrogen splitting, leading to the formation of the stable tetrahydroanthracen-1-ylium cation. The reactivity of the hydrogen splitting process on different catalytic centers is influenced by the local electric field generated by the hydride acceptor and proton acceptor within the frustrated Lewis pair sites.

Summary: This study presents a method to construct catalysts with regulable acidity and basicity by utilizing the Mott-Schottky effect on an intermetallic alloy. The developed fct-PtCo@NC catalyst with high-density frustrated Lewis pair (FLP) sites shows outstanding performance in the hydrogen evolution reaction. The synergistic effect of FLP-acid sites and FLP-base sites significantly reduces the energy barrier between water adsorption and decomposition, resulting in faster reaction kinetics.

Summary: The oxygen-bridged frustrated Lewis pairs (FLPs) underwent selective complexation with azobenzene under UV irradiation. The adduct of the second FLP was stable, while the adduct of the first FLP showed a [3,3]-rearrangement resembling ortho-benzidine. Similar rearrangements were observed with different para-substituted azobenzenes and di(2-naphthyl)diazene, but not with ortho-methylated azo compounds. The characterization of all adducts was done by multinuclear NMR spectroscopy and elemental analyses, and the rearrangement mechanism was explored using quantum-chemical calculations.

Summary: An improved synthesis method for 1,8-bis(dimethylboranyl)naphthalene without the use of tin(iv) reagents was developed. The reaction between 1 and 3 resulted in the formation of a frustrated Lewis pair (FLP) that reacted with protic compounds. The mechanisms of formation were explored and the stability of the adducts was investigated.

Summary: Despite recent progress in the chemistry of frustrated Lewis pairs (FLPs), direct FLP-catalyzed hydrogenation of CO2 remains elusive. The authors propose a mapping method to link the chemical composition of FLPs with their activity in catalytic hydrogenation of CO2, and they experimentally validate a combination with high catalytic turnover.

Summary: Frustrated Lewis pairs (FLPs) have been extensively studied in the field of chemistry. In addition to their use in small molecule activation reactions, FLPs also show promise as chelating ligands. Through a donor-acceptor approach, FLPs can stabilize low oxidation state centers and reactive molecular fragments, playing an important role in main group element chemistry.
