N2 - Palladium catalysts form a cornerstone of modernchemistry with upmost scientific and industrial impact. Bulkpalladium metal itself is chemically inert, and a sequence ofchemical transformations has to be utilized to convert the metal intoPd pre-catalyst covered by ligands. However, the “cocktail” ofcatalysis concept discovered recently has shown that Pd systemscan efficiently operate in catalysis without the necessity of acomplicated and expensive pre-installed ligand environment. Here,we point out on a green and sustainable process for Pd activespecies generation without the need of waste-abundant pre-catalystrelatedchemistry. In this work, an electric current was used togenerate an active Pd catalyst from a bulk metal in an ionic liquidmedium for the efficient cross-coupling of aryl iodides/bromides andboronic acids. Synthetically important Suzuki cross-coupling wasutilized as a representative test reaction to confirm the idea. It shouldbe emphasized that electric current is used only at the Pd dissolutionstage. Afterwards, the electrodes are removed from the reactionmixture and a standard reaction procedure can be followed. Thereported catalyst preparation process via electrochemical dissolutionis potentially compatible with a number of already existing catalyticmethods.
