In 2022,Chahkamali, Farhad Omarzehi; Sobhani, Sara; Sansano, Jose Miguel published an article in Catalysis Letters. The title of the article was 《Water-Dispersible Pd-N-Heterocyclic Carbene Complex Immobilized on Magnetic Nanoparticles as a New Heterogeneous Catalyst for Fluoride-Free Hiyama, Suzuki-Miyaura and Cyanation Reactions in Aqueous Media》.Reference of 4-Fluorobenzonitrile The author mentioned the following in the article:
Pd-N-heterocyclic carbine complex immobilized on magnetic nanoparticles was synthesized and characterized by different techniques such as FT-IR, XPS, TEM, EDX, FESEM, VSM, TGA and ICP. The synthesized catalyst was used as a new water dispersible heterogeneous catalyst in the fluoride-free Hiyama, Suzuki-Miyaura and cyanation reactions in pure water. By this method, different types of biaryls and aryl nitriles were synthesized in good to high yields by the reaction of a variety of aryl iodides, bromides and chlorides with triethoxyphenylsilane, phenylboronic acid and K4[Fe(CN)6]·3H2O, resp. The presence of sulfonates as hydrophilic groups on the surface of the catalyst confers a highly water dispersible, active and yet magnetically recoverable Pd catalyst. The possibility to perform the reaction in water as a green medium, ease of the catalyst recovery and reuse by magnetic separation, and the absence of any additives or co-solvents make this method as an eco-friendly and economical protocol for the synthesis of biaryl derivatives and aryl nitriles.4-Fluorobenzonitrile(cas: 1194-02-1Reference of 4-Fluorobenzonitrile) was used in this study.
4-Fluorobenzonitrile(cas: 1194-02-1) is used as chemical intermediate, solvent for perfumes and pharmaceuticals, stabilizer for chlorinated solvents, HPLC analysis, catalyst and component of transition-metal complex catalysts.Reference of 4-Fluorobenzonitrile
