《Palladium nanoparticles anchored polydopamine-coated graphene oxide/Fe3O4 nanoparticles (GO/Fe3O4@PDA/Pd) as a novel recyclable heterogeneous catalyst in the facile cyanation of haloarenes using K4[Fe(CN)6] as cyanide source》 was written by Veisi, Hojat; Tamoradi, Taiebeh; Rashtiani, Asra; Hemmati, Saba; Karmakar, Bikash. SDS of cas: 623-00-7 And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2020. The article conveys some information:
Pd(0) nanoparticles stabilized over polydopamine (PDA) capped magnetic GO/Fe3O4 nanocomposites (GO/Fe3O4@PDA/Pd) have been synthesized in variable Pd load following a post grafting approach. Pd has been reduced in situ by the functionalized PDA avoiding the use of external harsh reductant. The structural properties of the synthesized materials were studied by different anal. techniques like Field Emission SEM (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), High Resolution Transmission Electron Microscopy (HRTEM), Fourier Transformed IR (FT-IR) spectroscopy, Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), Thermo Gravimetric Anal. (TGA), Powder X-Ray Diffraction (XRD) and XPS. The novel GO/Fe3O4@PDA/Pd(0) nanocomposite exhibited excellent performance as a reusable catalyst in the facile cyanation of aryl halides using K4[Fe(CN)6] as a low cost and safe cyanating agent. The aryl nitriles were obtained in good to excellent yields and the catalyst was recycled up to 13 times with minimal change in its catalytic activity. In the experiment, the researchers used many compounds, for example, 4-Bromobenzonitrile(cas: 623-00-7SDS of cas: 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,SDS of cas: 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.
