Ionic liquids (ILs) have unique physicochemical properties that make them advantageous for catalysis, such as low vapor pressure, non-flammability, high thermal and chemical stabilities, the ability to enhance activity stability of (bio)catalysts. ILs can improve efficiency, selectivity, sustainability bio(transformations) by acting activators enzymes, selectively dissolving substrates products, reducing toxicity. They also be recycled reused multiple times without losing their effectiveness. based on imidazolium cation are preferred structural organization aspects, with a semiorganized layer surrounding catalyst. act container, providing confined space allows modulation electronic geometric effects, miscibility reactants residence time species. stabilize ionic radical species control catalytic dynamic processes. Supported IL phase (SILP) derivatives polymeric (PILs) good options molecular engineering greener The major factors governing metal, photo-, electro-, biocatalysts in discussed detail vast literature available over past two half decades. Catalytic reactions, ranging from hydrogenation cross-coupling oxidations, promoted homogeneous heterogeneous catalysts both single multiphase conditions, extensively reviewed considering knowledge accumulated until now.

Due to their unique structural and mechanical characteristics, zeolites are of great interest as carriers for the design catalysts. This review is focused on progress in development new zeolite-based catalysts hydroformylation. The procedures materials synthesis modification, methods metal introduction, effect catalyst structure activity, selectivity, stability hydroformylation discussed. highlights role up-to-date analytical techniques fine-tuned active selective greatest achievements over past five years considered detail this demonstrate a high potential Future prospects possible directions upcoming studies regarded.

Abstract The valorization of carbon dioxide as a C1 building block in C−C bond forming reactions is critical link on the road to carbon‐circular chemistry. Activation this inert molecule through reduction with H 2 monoxide reverse water‐gas shift (RWGS) reaction can be followed by wide spectrum consecutive carbonylation reactions, but RWGS severely equilibrium limited at moderate temperatures carbonylations. Here we successfully reconcile both one pot, while avoiding incompatibilities zeolite‐based compartmentalized approach. More specifically, Pt encapsulated small‐pore LTA zeolite selectively generates mild conditions; an ensuing one‐pot allows continuous consumption CO. Moreover, encapsulation avoids undesired like hydrogenation olefin reactant molecular sieving effect. This strategy was first studied in‐depth for Rh‐catalyzed hydroformylation CO /H , affording aldehydes good yields high regioselectivities. methodology then extended variety carbonylations using synthesis bulk and fine chemicals.
