Special Issue Information

Dear Colleagues,

We are calling for potential contributions for this Special Issue, “State-of-the-Art Polymerization Catalysis”. This Special Issue will cover recent trends in metal-catalyzed polymerization, including olefin coordination insertion polymerization, metathesis polymerization, ring-opening polymerization, condensation polymerization, etc. This Special Issue thus includes (i) the synthesis of functional materials (polymers) by olefin polymerization and efficient carbon–carbon bond formation; (ii) the synthesis of metal complex catalysts for olefin polymerization/oligomerization; (iii) metal-catalyzed polymerizations; and (iv) organometallic reactions related to efficient carbon–carbon bond formation. The design of molecular catalysis clearly plays a very important role in the synthesis of functional materials through precise olefin polymerization. These efforts aim to contribute toward the development of sustainable green chemistry and a circular economy.

We hope this topic is of interest to you as we are taking the opportunity to look at recent developments as well as explore the future scope in this field.

If you would like to submit papers to this Special Issue or have any questions, please contact the in-house editor, Mr. Ives Liu ([email protected]).

The efficient hydrogenation of N-heterocycles with H2 under mild conditions remains a significant challenge. In this work, polyphosphazene (PZs) microspheres, novel organic–inorganic hybrid materials possessing unique –P=N– structural units and a diverse range of side groups, were used to serve as support for the design of a stable and efficient Pd nanocatalyst (Pd/PZs). The PZs microspheres were prepared by self-assembly induced by precipitation polymerization, and Pd nanoparticles were grown and loaded on the support by a chemical reduction process. Several characterization techniques, including XRD, FTIR, SEM, TEM, XPS, BET and TGA, were used to study the structural features of the nanocomposites. The results revealed that Pd nanoparticles were uniformly distributed on the PZs microspheres, with primary sizes ranging from 4 to 9 nm based on the abundance of functional P/N/O groups in PZs. Remarkably high catalytic activity and stability were observed for the hydrogenation of quinoline compounds using the Pd/PZs nanocatalyst under mild conditions. Rates of 98.9% quinoline conversion and 98.5% 1,2,3,4-tetrahydroquinoline selectivity could be achieved at a low H2 pressure (1.5 bar) and temperature (40 °C). A possible reaction mechanism for quinoline hydrogenation over Pd/PZs was proposed. This work presents an innovative approach utilizing a Pd-based nanocatalyst for highly efficient multifunctional hydrogenation. Full article
