چکیده
Novel palladium, rhodium, iron, ruthenium and nickel half-sandwich picolinamide complexes have been prepared characterised in detail using high-resolution electrospray ionisation mass spectrometry (HR-ESI-MS), multi-dimensional nuclear magnetic resonance spectroscopy, elemental analysis (EA), Fourier transform-infrared spectroscopy (FT-IR), single crystal X-ray diffraction (SCXRD). All the systems proved to be active with good catalytic performance for hydrogenation of furfural. Among pre-catalyst, C2 (Rh metal centre) displayed complete conversion (100%). Pre-catalyst C5 (Ru also resulted excellent selectivity EL (51%) FA (49%). pre-catalysts early transition centres (Ni, Fe) gave towards (100%) under optimal conditions. Possible pathways formation catalytically proposed based on situ NMR studies obtained C2. Successful modification molecular (C2 C3) SBA-15 supported ([email protected] [email protected]). Furthermore, catalysts were inductively coupled plasma-optical emission (ICP-OES), Fourier-transform infrared powder (PXRD), BET surface area, selected area electron (SAED), photoelectron (XPS) transmission microscopy (HR-TEM). The complex was recycled five times (with consistent activity selectivity).
