Akkoc, Mitat; Bugday, Nesrin; Altin, Serdar; Kiraz, Nadir; Yasar, Sedat; Ozdemir, Ismail published their research in Journal of Organometallic Chemistry in 2021. The article was titled 《N-heterocyclic carbene Pd(II) complex supported on Fe3O4@SiO2: Highly active, reusable and magnetically separable catalyst for Suzuki-Miyaura cross-coupling reactions in aqueous media》.Related Products of 623-00-7 The article contains the following contents:
A new type magnetic nano Fe3O4@SiO2@NHC@Pd-MNPs heterogeneous catalyst was fabricated and characterized by Fourier Transform IR (FTIR) spectroscopy, Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), XPS, Energy Disperse X-ray anal. (EDX), Thermogravimetric Anal. (TGA), DTA (DTA), and SEM (SEM). The loading amount of palladium (Pd) to magnetic nano Fe3O4@SiO2@NHC@Pd-MNPs was measured by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) anal. The catalytic activity of magnetic nano Fe3O4@SiO2@NHC@Pd-MNPs heterogeneous catalyst was examined on Suzuki-Miyaura cross-coupling reactions of aryl halides with different substituted arylboronic acid derivatives All coupling reactions yielded excellent results and high TOF (up to 76528 h-1) in the presence of 2 mg of Fe3O4@SiO2@NHC@Pd-MNPs catalyst (0.0197 mmolg-1, 0.00394 mmol%Pd) at 80° in 2-propanol/H2O (1:2). In addition, the magnetic nano Fe3O4@SiO2@NHC@Pd-MNPs catalyst was easily recovered by using an external Nd-magnet and reused for the Suzuki cross-coupling reactions. The catalyst showed strong structural and chem. stability and was reused six times without losing its catalytic activity substantially. In the experimental materials used by the author, we found 4-Bromobenzonitrile(cas: 623-00-7Related Products of 623-00-7)
4-Bromobenzonitrile(cas: 623-00-7) is classified as organic nitriles, which are commonly use solvents and are reacted further for various applications such as manufacture of polymers and intermediates for pharmaceuticals and other organic chemicals,Related Products of 623-00-7 It can also be used as an aryl halide test compound in developing greener reaction conditions for Suzuki cross-coupling between aryl halides and phenyl boronic acid.
