Abstract
The use of palladium nanoparticles stabilized by natural beads made of an alginate/gellan mixture in the Suzuki-Miyaura cross-coupling reaction of arenediazonium tetrafluoroborates with potassium aryltrifluoroborates (1 : 1 molar ratio) with loading as low as 0.01–0.002 mol% under aerobic, phosphine-, and base-free conditions in water is described. The catalyst system can be reused several times without significant loss of activity.
