Applications to Suzuki–Miyaura reactions involving highly funtionalized reaction partners are demonstrated, all run using environmentally benign nanoreactors in water at ambient temperatures. Comparisons with existing state‐of‐the‐art ligands and catalysts are discussed herein.

  1087 An iron preparation substantially lowers the quantity of palladium needed to catalyze a common reaction that forms C-C bonds. Most of today’s use of transition metal–catalyzed cross-coupling chemistry relies on expensive quantities of palladium (Pd). Here we report that nanoparticles formed from inexpensive FeCl3 that naturally contains parts-per-million (ppm) levels of Pd can catalyze Suzuki-Miyaura
