Over the last decades, palladium has been appreciated as one of the most useful and versatile metals in organic synthesis, particularly for C–C bond formation, as acknowledged by the Nobel prize award in 2010. Palladium can take part in different processes such as oxidative additions and reductive eliminations, carbometalations, migratory insertions and nucleophilic substitutions. Some of these processes are key steps in important palladium-catalyzed organic reactions leading to the formation of C–C or C–heteroatom bonds.
We are interested in studying unusual types of palladium compounds (which are expected to show an unprecedented chemical behavior) and investigating their reactivity towards unsaturated molecules (alkenes, alkynes, arynes, conjugated dienes or allenes) in order to give rise to useful new methods in organic synthesis.
Some reciently published results are depicted in the following scheme:

Organometallic Gold Complexes in Synthesis, Catalysis and Supramolecular Chemistry

Involved researchers:

  • Prof. Dr. José Vicente
  • Dr. Juan Gil-Rubio
  • Dr. Verónica Cámara Hernández
  • María Blaya Muñoz

Our goal to increase the knowledge on the organometallic chemistry of Au(III) with the discovery of new types of compounds and reactions. This should provide a deeper insight into the mechanism of Au(I)/Au(III) catalyzed processes and help to develop new catalytic processes. Special attention is focused on fluorinated organometallic gold complexes.

We are also studying self-assembly processes between functionalized Au(I) complexes and metal ions or complexes. In these systems we have discovered new types of supramolecular structures where Au-Au interactions play an important role.

Photophysical Properties and Photochemistry of Organoplatinum Complexes

Involved researchers:

  • Dr. Pablo González-Herrero
  • Fabio Juliá Hernández

This project is aimed at the development of new organoplatinum complexes and the study of the their photophysical properties and excited-state reactivity. Our recent studies have focused on the synthesis and luminescence of homo- and heteroleptic tris-cyclometalated platinum(IV) complexes with heteroaromatic ligands. These complexes feature a unique combination of high-energy and highly efficient emission from long-lived triplet ligand-centered states with a highly oxidizing character in the excited state, which make them very promising as photocatalysts.
