Andrés Suárez studied Chemistry at the University of Sevilla (1992-1997). In 1997, he started a PhD Thesis at the Instituto de Investigaciones Químicas (CSIC-Universidad de Sevilla), carrying out research in the field of enantioselective catalysis, more specifically in synthesis of new chiral phosphorous ligands and their applications in enantioselective hydrogenation and hydroformylation reactions. After receiving his PhD, he undertook postdoctoral studies at the group of Prof. Gregory C. Fu (Massachusetts Institute of Technology, 2003-2004). In 2005, he returned to the Instituto de Investigaciones Químicas, in which he holds a permanent position since 2006, initially as R&D Technician and currently as Tenured Scientist. He has been visiting researcher at ICCOM-CNR (Florence, 2002, Prof. Maurizio Peruzzini) and at the Universities of Oxford (2002, Dr. John M. Brown) and Heidelberg (2013, Prof. Lutz H. Gade).

Current Research Areas

Metal complexes incorporating proton-responsive lutidine-derived pincer ligands.

  • Lutidine-derived pincer ligands are an interesting class of derivatives that may get involved in metal-ligand cooperation in a catalyic or stoichiometric process. So far, we have studied systems based on CNC, CNP and CNN pincers (C = N-heterocyclic carbene, P = phosphine, N = amine) that have been employed in a diversity of (de)hydrogenation reactions for organic synthesis and H2-storage, as well as in hydrosilylation and hydroboration reactions.
