Abstract Metal coordination polymers are widely applied in the synthesis of heterocyclic compounds due to advantages highly dispersed metal active sites, low cost and strong designability. Herein, employing 9‐benzyl‐3,6‐di( 1H ‐pyrazol‐1‐yl)‐ 9H ‐carbazole (BPC) as a ligand, cadmium‐coordinated polymer compound (Cd‐BPC) was facilely prepared by solvothermal method characterized energy dispersive spectrometer (EDS), flourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscope (SEM), transmission microscopy (TEM) X‐ray photoelectron spectrometry (XPS). Employing Cd‐BPC catalyst, 1,5‐benzodiazepine derivatives were produced with relatively high yields through reaction o ‐phenylenediamine ketones, alcohols. Additionally, could be reused for at least 5 times without significant decrease.

Construction of a C-C bond via alkylation ketones with alcohol as the alkylating source by employing hydrogen-borrowing strategy is attracting significant attention and highly appealing due to its simplicity, cost-effectiveness, environmental benefits, fact that water only byproduct. The development heterogeneous catalysts based on nonprecious base metals progressing rapidly. Our newly disclosed manganese-doped cerium oxide nanocomposite (10 wt % Mn@CeO2) stands out cost-efficient air-stable catalyst, synthesized through straightforward coprecipitation method employed for α-alkylation primary alcohols strategy. X-ray diffraction (XRD) analysis confirms high crystallinity CeO2, while field emission scanning electron microscopy (FE-SEM) high-resolution transmission (HR-TEM) images reveal MnO2 nanoparticles, measuring 19 nm in size, uniformly decorated rod-shaped CeO2 which have size 33 nm. photoelectron spectroscopy (XPS) uncovers presence Mn4+ species embedded nanorods. Electron paramagnetic resonance (EPR) further indicates surface defects contribute impressive catalytic yield, ranges from 70 98% α-alkylated ketones. Thermogravimetric (TGA) demonstrates remarkable thermal stability maintaining up 800 °C. Additionally, inductively coupled plasma mass spectrometry (ICP-MS) no leaching Mn ions, emphasizing heterogeneity catalyst. Remarkably, 10 Mn@CeO2 recycled six cycles loss activity. This study underscores synergistic effect between metal redox pair key exceptional activity reactions, making promising catalyst sustainable efficient formation.

Abstract A sustainable upgrading of renewable bulk materials, obtained by decomposition biomass lignocellulose, could facilitate their use in the industrial production chemicals. Homogeneous ruthenium catalysis plays a fundamental role this area. The review deals with upgradation lignocellulosic molecules through formation new C−C and C−N bonds. Selected examples catalytic bond forming reactions reported until mid 2023, include: (a) dehydrogenative based couplings alcohols, (b) reductive amination carbonyl compounds, (c) direct C−H functionalization (hetero)aromatic compounds. These approaches fulfill requirements sustainability: application occurs without any previous substrate activation, thus reducing waste. New chemicals containing intrinsic molecular structure lignocellulose substrates, showed broad range applications: green fuels, hydrogen carriers, monomers polymers, intermediates fine pharmaceuticals. results discussed inspire reader to improve valorization process, terms bio‐substrate scope as well product complexity, more strategic applications methods.
