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.
