Insight in the Alginate Pd-IonogelsApplication to the Tsuji–Trost Reaction

A new class of catalytic ionogels based on the entrapment of an ionic liquid phase within a sodium alginate matrix was applied to the Pd-catalyzed allylic substitution reaction. High activity and promising recyclability were obtained in C–N bond formation. Scanning electron microscopy, scanning transmission electron microscopy, and solid-state NMR studies provided a better insight into the catalytic behavior, and the stability of the catalytic ionogels was studied through a recycling process
