Cycloadditions and cyclization reactions via post-synthetic modification and/or one-pot methodologies for the stabilization of mine-based covalent organic frameworks Gala Sánchez, Elena Ramos, M. Mar Segura Castedo, José Luis 547 Covalent organic frameworks Post-synthetic modification One-pot synthesis Stabilization Imine-based-COFs Cycloaddition reaction Povarov reaction Aza-Diels–Alder Oxidative cyclization Química orgánica (Química) 2306 Química Orgánica 2023 Descuentos MDPI Interest in covalent organic frameworks as high-value materials has grown steadily since their development in the 2000s. However, the great advantage that allows us to obtain these crystalline materials—the reversibility of the bonds that form the network—supposes a drawback in terms of thermal and chemical stability. Among the different strategies employed for the stabilization of imine-based Covalent Organic Frameworks (COFs), cycloaddition and other related cyclization reactions are especially significant to obtain highly stable networks with extended π-delocalization and new functionalities, expanding even further the potential application of these materials. Therefore, this entry gathered the most recent research strategies for obtaining stable COFs by means of cyclization reactions, including the Povarov reaction and intramolecular oxidative cyclization reactions as well as some other recent innovative approaches.
