The complexes containing the ligands Tp(Br3) or Tp(Ms) have provided activities and selectivities for these transformations comparable with or, in some cases, better than the well-known rhodium catalyst Rh(2)(OAc)(4)}, organization = {We thank the MEC (Proyecto CTQ2008-00042/BQU) and the Junta de Andalucía (Proyecto P07-FQM-02794) for financial support.
