Summary: A new series of Cu(II) and Mn(II) complexes with Schiff base ligands derived from 2-furylmethylketone (Met), 2-furaldehyde (Fur), and 2-hydroxyacetopheneone (Hyd) have been synthesized on functionalized SBA-15-NH2, MCM-48-NH2, and MCM-41-NH2 supports. The hybrid materials were characterized by various techniques and their catalytic performances in oxidation reactions were evaluated. The best catalytic activity was observed for the SBA-15-NH2-MetMn catalyst in the oxidation of cyclohexene, and no leaching was observed for Cu and Mn complexes.

Summary: A copper (II) Schiff base complex supported on multi-walled carbon nanotubes (MWCNTs-Cu) has been successfully prepared and characterized. The complex was used as a heterogeneous catalyst for the selective oxidation of benzyl alcohol derivatives to benzaldehydes. The optimized reaction conditions were found to be 1,4-Dioxane as solvent, 1 mmol of tert-BuOOH as oxidizing agent, and 0.05 g of MWCNTs-Cu as a catalyst at 80 degrees C. The catalyst showed good reusability without significant loss of its activity.

Summary: In this study, Pt nanoparticles modified Mn doped Bi4Ti3O12 ultrathin nanosheets (Pt/MnNS) were constructed as a surface functionalized photocatalyst for visible-light-driven selective benzyl alcohol (BA) oxidation. Among them, Pt/5MnNS showed the best performance with a benzaldehyde (BD) yield rate of 1180 μmol·g-1·h-1 and a selectivity of 99.9%. Experimental results revealed that Mn doping extended the optical absorption range of the photocatalyst to the visible region and induced the formation of more surface Ti4+d atoms. These Ti4+d atoms served as stronger Lewis acid centers, achieving more prominent adsorption and activation of BA, making it easier to deprotonate BA by photogenerated holes. Meanwhile, Pt nanoparticles significantly promoted the separation and transfer of photogenerated carriers, supporting the formation of superoxide and carbon-centered radicals. Thus, the photocatalytic BA oxidation efficiency was markedly improved by surface multicomponent synergistic effect.

Summary: Oxidative deamination of benzyl amines is achieved using a Ni(ii)-NHC catalyst with water in aqueous medium, resulting in the formation of aldehydes. Water acts as a formal oxidant in this process. The presence of hemilabile pyridyl units in the catalyst facilitates the approach of amines to the metal, allowing nucleophilic water attack on the metal-bound imine. This water-soluble 3d-metal Ni(ii) catalyst with promoter ligands provides a new avenue for water-mediated oxidation reactions.

Summary: Two new dinuclear complexes of Zn2+ ion (ZnLC2 and ZnLC6) with novel diisatin dihydrazone ligands were constructed and confirmed by spectroscopic tools. ZnLC6 showed higher catalytic activity in the oxygenation protocol of benzyl alcohol. The biological action of ZnLCX complexes against microbial species, human cancer cells, and ctDNA was investigated, and they exhibited stronger inhibitory effects compared to the free ligands.

Summary: The structural characteristics of a series of copper(II) complexes were investigated using spectroscopic and analytical methods. The crystal structures of aroylhydrazone, APMB and copper complex 4 were resolved using single-crystal X-ray diffraction studies. The copper(II) complexes showed promising catalytic activity in the oxidation of cinnamyl alcohol, with complex 1 exhibiting the highest activity.

Summary: Selective oxidation of benzyl alcohols to carbonyl compounds is crucial for the synthesis of pharmaceuticals and fine chemicals. In this study, a CsPbBr3/Ni4P2 composite was constructed for efficient photocatalytic conversion of benzyl alcohol to benzaldehyde with high selectivity. Mechanistic studies revealed the crucial role of Ni4P2 in charge separation/migration and utilization.

Summary: Cu(II) catalysts in homogeneous and heterogeneous form were synthesized and their reactivity in selective oxidation of benzyl alcohol and catechol oxidation was investigated. The single site Cu(II) catalyst showed superior activity in benzyl alcohol oxidation, while the dinuclear systems were more preferred for catechol oxidation. Experimental and theoretical studies provided insights into the reaction mechanism and the formation of Cu-CH3CN complex and Cu-hydroperoxo species during the oxidation processes.

Summary: In this study, different-sized Ni nanoparticles supported on nitrogen-doped carbon were synthesized by controlling the pyrolysis temperature. The electrooxidation of benzyl alcohol over these nanocatalysts showed varying performance, which was attributed to the difference in adsorption strength of reactant molecules.
