“…Using CO 2 as a green C1 chemical feedstock to produce valuable chemicals is considered a promising method to reduce this greenhouse gas and achieve carbon neutrality . Considering the high solvent stability of FIR-137, the chemical fixation of CO 2 into cyclic carbonates was chosen as a model reaction to check its catalytic activity. , …”

Titanium-based metal−organic frameworks (Ti-MOFs) are one of the most active fields of MOFs due to their intriguing catalytic properties; however, the fast reaction between the widely used carboxylate-based ligand (hard base) and Ti 4+ ion (hard acid) makes the syntheses of Ti-MOFs extremely challenging. In this work, we propose a new strategy by adopting sulfonic acid (soft base) as organic ligands to synthesize Ti-MOFs based on hard and soft acid and base (HSAB) theory. As an example of this strategy, seven titanium sulfonate metal−organic frameworks have been synthesized from 1,5-naphthalenedisulfonic acid (H 2 nds) and titanium isopropoxide and their structures are determined by single-crystal X-ray diffraction. These compounds exhibit permanent porosity, solvent stability, and light adsorption ability with a narrow band gap (2.67 eV). This work demonstrates a powerful method for the single-crystal syntheses of new Ti-MOFs, which will greatly promote the development of Ti-MOFs.

“…The use of bifunctional and binary catalysts (i.e., catalytic systems containing two different kinds of catalytically active moieties in the same molecule/material or in two distinct molecules, respectively) is known to lead to significant enhancements of reactions rates in the cycloaddition of CO 2 to epoxides. ,, Typical examples of bifunctional/binary systems include metal complexes with halide- ,, or N -nucleophiles. , In organocatalysis, HBDs with halide- , or N -nucleophiles , are often encountered. Mechanistically, as shown in Scheme , such bifunctional systems mainly cooperate in the step of epoxide ring-opening.…”

The catalytic cycloaddition of CO2 to epoxides to afford cyclic carbonates as useful monomers, intermediates, solvents, and additives is a continuously growing field of investigation as a way to carry out the atom-economic conversion of CO2 to value-added products. Metal-free organocatalytic compounds are attractive systems among various catalysts for such transformations because they are inexpensive, nontoxic, and readily available. Herein, we highlight and discuss key advances in the development of polymer-based organocatalytic materials that match these requirements of affordability and availability by considering their synthetic routes, the monomers, and the supports employed. The discussion is organized according to the number (monofunctional versus bifunctional materials) and type of catalytically active moieties, including both halide-based and halide-free systems. Two general synthetic approaches are identified based on the postsynthetic functionalization of polymeric supports or the copolymerization of monomers bearing catalytically active moieties. After a review of the material syntheses and catalytic activities, the chemical and structural features affecting catalytic performance are discussed. Based on such analysis, some strategies for the future design of affordable and readily available polymer-based organocatalysts with enhanced catalytic activity under mild conditions are considered.

Cycloaddition of di-substituted epoxides and CO₂under ambient conditions catalysed by rare-earth poly(phenolate) complexes

Abstract: Lanthanum complex 1/TBAI is the first catalyst to achieve the cycloaddition of 1,2-disubstituted epoxides with 1 bar CO2 at room temperature. A DFT study discloses that the poly(phenolato) ligand plays a key role in the product dissociation step.
