One use of CO2 as a starting material in organic transformations is the synthesis cyclic carbonates and polycarbonates. Due to low reactivity CO2, this transformation must be carried out presence an efficient catalyst. Although several catalytic systems have been developed past decade, reducing pressure at which reaction remains one main challenges process. In context, present work, we describe activity mixed metal oxides from (1 atm) epoxides 70 °C. Using these materials catalysts represents significant benefits since they are very stable, cost-effective, can reused cycles.

There is an increasing demand for the development of lanthanide metal-organic frameworks and derived multifunctional materials. The functional properties such compounds are influenced by arrangement various Lewis basic sites or structural configurations ligands. In this study, a series isostructural Ln-MOFs containing phosphine-dicarboxylate ligand, [Ln(HL)(L)(DMF)]·DMF (where H2L = 5-(diphenylphosphanyl)isophthalic acid, Ln Tb3+ (1), Eu3+ (2), Gd3+ (3), Ce3+ (4), Nd3+ (5)), was synthesized under solvothermal conditions characterized in detail. Among obtained compounds, Tb-MOF 1 demonstrated excellent luminescent with high quantum yield (90.45%) considerable lifetime (1266 μs). Furthermore, acts as unique sensor 4-formylphenylboronic acid 9-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]carbazole, exhibiting low detection limits 1.38 3.62 mM, respectively. Additionally, Nd-MOF 5 efficient catalyst coupling carbon dioxide to epoxy resulting conversion rates (up 96%). This study further extends growing family provides insights preparing materials through modification organic ligands specific groups.

Abstract Composite silica materials have been developed by hydrothermal method and utilized as heterogeneous Hydrogen Bond Donor (HBD) catalysts, where the functionalized ketimine derivatives immobilized on solid support. Such functional found to be efficient catalysts for synthesis of cyclic carbonates through installation CO 2 with epoxides. Characterization these was systematically done using various spectroscopic imaging techniques confirm presence organic compounds surface. These composite exhibited significantly higher catalytic activity compared other homogeneous methods. Additionally, this synthetic process extremely convenient in terms all external parameters such as, solvent free condition at ambient reaction temperature normal pressure , very low catalyst loading proper regeneration reusability catalyst. facets definitely made technique greener more sustainable.

The these materials catalysts represents great advantage since they are highly stable economical can reused cycles.
