A series of ionic liquid (IL), zinc halide (ZnX 2 ), and triphenylphosphine (PPh 3 ) integrated porous organic polymers (POPs) featuring multifunctional sites were afforded through solvothermal synthesis for cyclic carbonate synthesis which utilizes epoxides and carbon dioxide (CO 2 ). Owing to the cooperative effect of ionic liquid and homogeneously distributed Zn-PPh 3 specie, which is probably strengthened by the confined microporous structure and flexible frameworks, these POPs catalysts exhibited high CO 2 capture and conversion performance and provided the highest activity (initial turnover frequencies up to 5200 h −1 ) of heterogeneous catalysts reported to date within the context of cyclic carbonate formation. Even more surprising, very favorable turnover numbers (TONs) of 2120 and 720 were attained at 40 and 25 °C, respectively. The effect of reaction parameters (reaction time, temperature, CO 2 pressure) on the catalytic performance as well as other epoxide substrates were also investigated in detail. Furthermore, the catalyst can be easily recovered and reused five times without a significant loss of activity. These ionic liquid and Zn-PPh 3 constructed porous polymers may provide an industrial opportunity for cyclic carbonate products.

The hydroformylation of propene to linear-butaldehyde can be performed efficiently in a continuous fixed-bed reactor employing the copolymer self-supported heterogeneous Rh/CPOL-bp&P catalysts.

A single-component multifunctional catalyst (denoted as Mg-por/pho@POP) based on a magnesium porphyrin and phosphonium salt-integrated porous organic polymer (POP) was afforded via a solvothermal synthetic technique for cyclic carbonate production which uses epoxides and CO2. In consequence of the cooperative (or synergistic) effect of a phosphonium salt and homogeneously dispersed magnesium porphyrin moiety, which is possibly reinforced through the flexible frameworks and confined microporous structure, this powerful catalyst offered the highest activity of a heterogeneous catalyst within the context of cyclic carbonates synthesis from epoxide and CO2 (turnover frequencies up to 15,600 h–1) without the addition of co-catalysts. More surprisingly, very promising turnover numbers (TONs) of 14,400 and 4200 were realized at very mild temperatures of 25 and 40 °C. Moreover, Mg-por/pho@POP can be simply recovered and reused at least five times.

A new type of phosphorus‐doped porous organic polymer (POP) has been readily synthesized through a Heck reaction, which could be used not only as a support but also a ligand for palladium nanoparticles. The dual‐functional material supported palladium nanocatalyst was used for the efficient and chemoselective hydrogenation of varieties of nitroarenes and α,β‐unsaturated compounds, as well as for the synthesis of indoles from 2‐nitrophenylacetonitrile under 1 atm hydrogen in green solvents at room temperature. No obvious aggregation and loss of catalytic activity of the new nanocatalyst were observed after 10 runs in the reaction.magnified image

CO 2 as a C1 building block for the N-formylation reaction is attracting much attention. In general, the N-formylation reaction requires the participation of alkali, which can break the equilibrium to promote the reaction process. We developed a After Ru metalationheterogeneous catalyst with an alkaline functional group based on a porous organic polymer (denoted as Ru-PPh 3 -SO 3 Na@POPs) by the copolymerization of vinyl-functionalized PPh 3 (3v-PPh 3 ) and sodium-4vinylbenzenesulfonate. After Ru metalation, the catalyst obtained a high TON without the addition of alkali under mild conditions. The Ru-PPh 3 -SO 3 Na@POP catalyst can immobilize metals and alkali efficiently on porous organic polymers, showing excellent performance and good stability for the N-formylation reaction of amine and CO 2 .

Vinyl functionalized Biphephos ligand, denoted as vinyl biphephos, has been succesfully synthesized.

Replacement of noble metal catalysts with low‐cost, non‐noble heterogeneous catalysts is highly desirable. Herein, we prepared a reactive, inexpensive and stable isolated single‐atom Zn/N‐doped porous carbon (ZnNC) catalyst derived from a versatile zeolitic imidazolate framework precursor. The optimized ZnNC‐1000 with Zn‐Nx species possesses high zinc loading (5.2 wt%) and nitrogen content (6.73 wt%), exhibits efficient catalytic performance in the one‐pot N‐formylation of nitroarene to the corresponding formamides by using formic acid as the hydrogen donor and formylation agent. H2‐D2 exchange reaction and HCOOH‐chemisorption experiments demonstrated that atomically dispersed Zn‐Nx species are essential for the activation of hydrogen and HCOOH molecules, which finally contributed to the highest catalytic activity of ZnNC‐1000 for the reductive N‐formylation reaction.
