Deposited zirconocene chloride on silica-layered CuFe2O4 as a highly efficient and reusable magnetically nanocatalyst for one-pot Suzuki-Miyaura coupling reaction

Publication date: Available online 30 December 2017 Source:Journal of Organometallic Chemistry Author(s): Behzad Zeynizadeh, Farhad Sepehraddin The novel core-shell magnetically nanoparticles of CuFe2O4@SiO2@ZrCp2Clx (x: 0–2) were synthesized and used as a highly efficient catalyst for Suzuki-Miyaura coupling reaction of various aryl halides with phenylboronic acid. The reactions were carried out in PEG-400 (70 °C) to afford biaryls in high to excellent yields. The core-shell nanocomposite was easily separated from the reaction by an external magnet and reused for 5 times without significant loss of its catalytic activity. Characterization of the zirconocene nanocomposite was carried out by FT-IR, SEM, EDX, XRD, ICP-OES, AGFM, TGA and BET analyses. Graphical abstract
