Witryna1 lis 2024 · Interfacial chemistry provides an opportunity to control dynamic materials. By harnessing the dynamic covalent nature of imine bonds, emulsions are generated in situ, predictably manipulated, and ultimately destroyed along liquid–liquid and emulsion–solid interfaces through simple perturbation of the imine equilibria. We report the rapid … Witryna13 mar 2024 · An insight into the reaction mechanism as shown in Scheme 2 suggested that the generation of the radical intermediate initiated the reaction, followed by the formation of imine B. Later, imine B reacted with 2-aminobenzylamine 4 to form intermediates C , D , and E successively.
