Summary: The application of heterogeneous catalysts in continuous-flow enantioselective hydroacylation reactions was studied. Catalysts were prepared by mixing supports and rhodium complexes, and showed excellent activity and enantioselectivity. Under optimized conditions, the catalysts exhibited high turnover numbers and could be applied to various substrates. Furthermore, sequential-flow reactions with other heterogeneous catalysts were demonstrated for the synthesis of biologically active molecules and functional materials.

Summary: This study reports the synthesis of hybrid nanocomposites with catalytic activity by combining polymer nanofibers and gold nanoparticles. The nanofibers were obtained through electrospinning blends of a poly (ionic liquid) and its precursor polymer. The results showed that the nanofiber characteristics depended on the proportion of polymer in the blends. The obtained nanofibers were used to synthesize gold nanoparticles on their surface, which significantly improved the performance of the nanofibers in ion adsorption and catalytic reactions.

Summary: This article describes the use of CO2 as a promising C1 source instead of CO in the tandem Pauson-Khand reaction. The reaction is achieved by combining the reduction of CO2 to CO using a metal organic framework (MOF) catalyst with homogeneous rhodium catalysts for the cycloaddition step. A range of substrates were converted in moderate to good yields.

Summary: The article introduces an alternative reaction pathway for the O-formylation of alcohols and bio-alcohols, which produces industrially relevant formate esters. The reaction is catalyzed by formic acid, which can be produced from CO2 captured in the reaction. The in situ produced formic acid improves the reaction rate, and each catalyst can be recycled for reuse.

Summary: Compared with Ru-II-arene compounds, the medicinal potential of homologous Ru-II-tpm compounds [tpm = tris(pyrazolyl)methane] is not well explored. A series of [RuCl(kappa(3)-tpm)(PPh3)(L)]Cl complexes were synthesized by reacting pyridine, 4-pyridinemethanol, and four functionalized pyridines with the precursor [RuCl(kappa(3)-tpm)(PPh3)(2)]Cl. The complexes exhibited antiproliferative activity against cancerous cell lines and inhibition towards COX-2 and GSTP1 enzymes.
