Evaluation of Nitrogen-Based Polymeric Heterogeneous Catalysts for the Suzuki–Miyaura Cross-Coupling Reaction in Water

Abstract

As environmental issues continuously increase, the development of effective and eco-friendly catalytic systems in organic chemistry is of great importance. To achieve this goal, two representative strategies are generally used: designing durable and efficient heterogeneous catalysts and using a clean and nontoxic solvent, such as water. Unfortunately, the interactions between widely used ligands and water have not been comprehensively investigated. Here, we first synthesized five similarly structured Nbased palladium-embedded polymers, Pd

Silver Iodide‐mediated Insertion of Indium to Synthesize Water‐tolerant Organoindium Reagents and the Application in Cross‐coupling Reactions

“…Thus, the good reactivity and high selectivity have proved silver salts as one of the most prominent types of catalysts in radical chemistry [18–20] . Due to its outstanding high reactivity and unique selectivity, AgI‐driven radical reactions provide a powerful route to synthesizing organic compounds with multifunctionality and step economy [21] . In conclusion, by comparing the four promoters, LiCl, InCl 2 , CuCl and AgI, it was shown that AgI has good reactivity and high selectivity as a promoter, and can improve the reaction yield by generating free radicals.…”

An Imidazole‐Rich Pd(II)‐Polymer Pre‐catalyst for the Suzuki‐Miyaura Coupling: Stability Influenced by Dissolved Oxygen and Reactants Concentration

“…[27] Compared to traditional supports, such as metal oxides or carbon, the support can be more easily tuned by inserting coordinating groups using simple chemical steps. [28][29][30][31][32][33][34] Among the myriad of heterogeneous supports for Pd immobilization, many contain the imidazole group as a key component. For example, Yamada and co-workers [35,36] synthesized a poly(imidazole)-based polymer that was used to encapsulate Pd(II).…”
