摘要

Abstract Different Pd-complexes (see 2a–d and 3) with and without 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 H 2 O. H 2 O- Soluble aryl bromides were easily converted to the corresponding biphenyls. Although none of the complexes is H 2 O-soluble, the active catalyst is most likely homogeneously ...
