Magnetic Nanoparticle Decorated N-Heterocyclic Carbene-Nickel Complex with Pendant Ferrocenyl Group for C-H Arylation of Benzoxazole
Magnetic nanoparticle decorated N-heterocyclic carbene-nickel complex with pendant ferrocenyl group has been prepared by multi-step procedure. The formation of complex was confirmed on the basis of analytical techniques such as Fourier transform infrared (FT-IR), Fourier transform Raman (FT-Raman) and X-ray photoelectron spectroscopy (XPS) as well as by X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) analysis. The complex proved to be an efficient heterogeneous catalyst for C-H arylation of benzoxazole with aryl boronic acids. The recycling studies revealed that complex could be reused for six times without significant decrease in catalytic activity. [GRAPHICS] .
