    Enhanced catalytic performance of silica-supported Pd-NHC complexes in Suzuki-Miyaura coupling reactions
    (Elsevier, 2025) Akkoc, Mitat; Koc, Hatice Kubra; Ozdemir, Ismail
    Since silica-supported catalysts are effective due to their rigid but porous structure, which lacks thermal and chemical stability and swelling properties, the characteristic structure of this heterogeneous catalyst we synthesized was elucidated using methods such as NMR, XRD, FTIR, SEM, DTA, and TGA. In this study, benzimidazolium salt was first synthesized and then converted into a Pd-NHC complex. The synthesized Pd-NHC complex was bonded to the SiO2 structure, and heterogeneous SiO2@NHC@Pd was synthesized. The Suzuki-Miyaura C-C coupling reaction of this SiO2@NHC@Pd catalyst was successfully carried out under mild conditions in the presence of green solvents.
