We have imparted Invited Lectures in meetings in Microwave Chemistry, Heterocyclic Chemistry, Green Chemistry and Materials Chemistry, for example, COST action on Reactions under Extreme and Non Classical Conditions (Chambéry, 1996), 2nd and 3rd International Conference on Microwave Chemistry (Prague, 1998 y Antibes, France 2000), 4th Green Chemistry Conference (Barcelone, 2002), Green Chemistry meeting (Barcelone, 2003), VIII Semana científica “Antonio González” (La Laguna, 2004), 3rd Microwave in Chemistry Conference (Orlando, 2005), 10th Internacional Conference on Microwave and High Frequency Heating (Modena, Italia, 2005), First Avogadro Symposium on Microwave Chemistry (Bergamo, Italia, 2005) (only eighteen specialized researchers on applications of microwave irradiation in chemistry were invited), Transmediterranean Colloquium on Heterocyclic Chemistry (TRAMECH-4). (Aveiro, Portugal, 2005), 50th anniversary of the Sociedad Mexicana de Química (Mexico D., 2006), First Congreso Mexicano de Química sustentable (Mérida, 2008) and 216th Meeting of the Electrochemical Society. Viena (Austria).

We have participated in International Scientific Committees in Congresses related to our research, for example: 2nd Internacional Conference on Microwave Chemistry (Praga, 1998), 5th Green Chemistry Conference (Barcelona, 2003), 8th International Electronic Conference on Synthetic Organic Chemistry (2004), 10th International Conference on Microwave and High Frequency Heating (Modena, Italia, 2005).

Our contribution in Microwave Assisted Organic Synthesis can be summarized in:

a) The results obtained by conventional heating have dramatically improved. Improved yields and shortened reaction times were observed.

b) Wide series of compounds with potential interest as ligands in Coordination Chemistry, or with application in Chemistry of materials and Supramolecular Chemistry have been prepared.

c) The design and development of new microwave instruments with higher power that the commercially available and cavities, and new glassware and methods under microwave irradiation and solvent-free conditions.

d) The design and application of used new flow systems coupled to NMR microcoils.

e ) The utility of solid supports under microwave irradiation have made evident with our research.

f) The utility of microwave irradiation in order to modify the selectivity of some reactions have been described.

g) We have used computational calculations to study microwave assisted reactions and we have developed a predictive model that can be used to predict when a reaction will be improved under microwave irradiation by thermal or non-thermal effects.

h) A methodology for the modification of carbon nanostructures under microwave irradiation have been designed, the excellent absorption of microwave radiation and the subsequent chemical activation have been shown.

i) Functionalization of carbon nanostructures with dendrimers under microwave irradiation has been applied with success to the preparation of compounds used in gene transfection.

Two of our researchers have been awarded with prizes, Premio Joven Investigadora “Ibn Wafid de Toledo“ 2009 form the Junta de Comunidades de Castilla-La Mancha and L’Oreal-UNESCO “For Women in Science” 2010.
