The Front Cover shows how in a few simple steps it is possible to extract palladium contained in electronic waste and employ it directly into catalyzed cross‐coupling reactions in water. Exploitation of the so‐called “urban mine” usually stumbles on the treatment of complex metal mixtures. A straightforward hydrometallurgical process was designed and efficiently applied to prepare palladium‐containing micellar solutions, readily usable for Suzuki–Miyaura cross‐coupling reactions, without the need to isolate the corresponding pure metallic salt. Judicious choice of a surfactant enables the extraction and the stabilization of palladium as Pd(II) in aqueous solutions that are employed as reaction media for micellar catalysis.
