Controllable preparation of phosphonium-based polymeric ionic liquids as highly selective nanocatalysts for the chemical conversion of CO2 with epoxides

A novel approach to overcoming the insulating properties of olivine 5 V electrode materials is realized in carbon-free LiCoPO4 thin films by tailoring its chemical composition via the incorporation of lithium cobalt triphosphate into the olivine phase, thereby forming a network of conductive channels. The cyclic voltammograms of the engineered material exhibited a redox potential of ≈4.8 V/4.9 V. The experimentally obtained energy diagram quantified the inductive effect which led to the increase of the redox energy by ≈1.0 eV in comparison to LiCoO2 layered oxide. Although the enhanced electronic conductivity and excellent electrochemical activity were obtained by using the thin film cathode material, the strategy of the design of olivine with triphosphate can be extended to more thick electrodes (>1 μm), giving a perspective for the development of 5 V all solid state batteries suitable for commercial application. The evident ability to exchange the charge of all Co2+ ions with lithiation/delithiation reaction and deliver high power in carbon free high voltage cathode material opens up new perspectives for the development of next generation of high energy density electrochemical storage devices.

Preparation method of cyclic carbonate

The invention belongs to the technical field of materials, and particularly relates to a preparation method of a cyclic carbonate, which takes a double-center porous polymer as a catalyst and catalysis CO. 2 The conversion is cyclic carbonate, and the double-center porous polymer is a double-center heterogeneous porous catalyst of metalloporphyrin and quaternary phosphonium sites. The invention solves the problem of complicated recovery of the catalyst for synthesis of the existing cyclocarbonate, utilizes the double-center porous polymer containing the metalloporphyrin and the quaternary phosphonium site as a catalyst to realize the combination and synergistic combination of the two active centers on the molecular level, thereby efficiently converting carbon dioxide into cyclic carbonate.

Method for synthesizing novel fluoride-free organic phosphine ligand modified by carbonate ester

The invention relates to the field of organic synthesis, and provides a method for synthesizing a novel fluoride-free organic phosphine ligand modified by carbonate ester. According the synthesis method, p-bromostyrene or derivatives of the p-bromostyrene are adopted as raw materials for preparing a Grignard reagent which reacts with a phosphorus source to produce a skeleton-structure molecule with triphenylphosphine, and after oxidation, epoxidation, cycloaddition, reduction are conducted, the target molecular structure can be obtained. The synthesis method has the advantages that by synthesizing the novel organic CO2-soluable phosphine ligand, the solubility of the phosphine ligand in supercritical CO2 is improved, so that the application of fluoride-free phosphine ligand- organo-metallic catalysts in the supercritical CO2 is realized; besides, due to the property that the organic carbonate ester compound is insoluble in weak or non-polar organic solvent, such as an alkane compound,the fluorine-free phosphine ligand modified by the carbonate group is provided with a function of phase separation in a reaction system so that the recovery and reuse of the catalysts can be achieved.

Frustrated Lewis Pair Polymers as Responsive Self-Healing Gels

Steric bulk prevents the formation of strong bonds between Lewis acids and bases in frustrated Lewis pairs (FLPs), where latent reactivity makes these reagents transformative in small molecule activations and metal-free catalysis. However, their use as a platform for developing materials chemistry is unexplored. Here we report a fully macromolecular FLP, built from linear copolymers that containing either a sterically encumbered Lewis base or Lewis acid as a pendant functional group. The target functional copolymers were prepared by a controlled radical copolymerization of styrene with designer boron or phosphorus containing monomers. Mixtures of the B- and P-functionalized polystyrenes do not react, with the steric bulk of the functional monomers preventing the favorable Lewis acid base interaction. Addition of a small molecule (diethyl azodicarboxylate) promotes rapid network formation, cross-linking the reactive polymer chains. The resulting gel is dynamic, can self-heal, is heat responsive, and can be reshaped by postgelation processing.

Highly efficient aqueous phase chemoselective hydrogenation of α,β-unsaturated aldehydes catalysed by phosphine-decorated polymer immobilized IL-stabilized PdNPs

Phosphino-decorated polymer immobilised ionic liquid phase stabilised palladium nanoparticles (PdNP@PPh2-PIILP) and their PEGylated counterparts (PdNP@PPh2-PEGPIILP) are remarkably active and exceptionally selective catalysts for the aqueous phase hydrogenation of α,β-unsaturated aldehydes, ketones, esters and nitriles with PdNP@PPh2-PEGPIILP giving complete conversion and 100% selectivity for reduction of the CC bond, under mild conditions. This is the most selective PdNP-based system to be reported for the aqueous phase hydrogenation of this class of substrates.

Flexibility Matters: Cooperative Active Sites in Covalent Organic Framework and Threaded Ionic Polymer

The combination of two or more reactive centers working in concert on a substrate to facilitate the reaction is now considered state of the art in catalysis, yet there still remains a tremendous challenge. Few heterogeneous systems of this sort have been exploited, as the active sites spatially separated within the rigid framework are usually difficult to cooperate. It is now shown that this roadblock can be surpassed. The underlying principle of the strategy presented here is the integration of catalytic components with excellent flexibility and porous heterogeneous catalysts, as demonstrated by the placement of linear ionic polymers in close proximity to surface Lewis acid active sites anchored on the walls of a covalent organic framework (COF). Using the cycloaddition of the epoxides and CO2 as a model reaction, dramatic activity improvements have been achieved for the composite catalysts in relation to the individual catalytic component. Furthermore, they also clearly outperform the benchmark catalytic systems formed by the combination of the molecular organocatalysts and heterogeneous Lewis acid catalysts, while affording additional recyclability. The extraordinary flexibility and enriched concentration of the catalytically active moieties on linear polymers facilitate the concerted catalysis, thus leading to superior catalytic performance. This work therefore uncovers an entirely new strategy for designing bifunctional catalysts with double-activation behavior and opens a new avenue in the design of multicapable systems that mimic biocatalysis.

A Polymer-Bound Monodentate-P-Ligated Palladium Complex as a Recyclable Catalyst for the Suzuki-Miyaura Coupling Reaction of Aryl Chlorides

A three-fold cross-linked polymer-bound phosphine (POL-Ph3P) with high phosphorus content has been prepared. The phosphorus-containing polymer forms a monodentate-P-ligated palladium complex, which shows excellent activity in Suzuki-Miyaura cross-coupling reactions of aryl chlorides. Importantly, the catalyst Pd/POL-Ph3P is highly stable and can be reused for at least 10 times without losing reactivity.

Threefold cross-linked polystyrene-triphenylphosphane hybrids: Mono-P-ligating behavior and catalytic applications for aryl chloride cross-coupling and C(sp3)-H borylation

Covalently bound polystyrene-phosphane hybrids were prepared by a method based on radical emulsion polymerization of styrenes in the presence of a tris(p-vinylphenyl)phosphane cross-linker. These hybrids favor mono-P-ligation to transition-metal complexes and are useful for challenging catalysis, such as Pd-catalyzed C-C/C-N couplings with unactivated chloroarenes and Ir- or Rh-catalyzed C(sp3)-H borylations.
