perfluoroalkyl tags were deposited on fluorous reversed-phase silica 1 and unmodified silica gel. These supported complexes were successfully used as precatalysts for the Suzuki reaction in H2O. H2O-Soluble aryl bromides were easily converted to the corresponding biphenyls. Although none of the complexes is H2O-soluble, the active catalyst is most likely homogeneously dissolved. Nevertheless, the Pd-leaching
