About the Multidisciplinary Seminar Program
Created in 1995, the Escola Tecnica Superior d'Enginyeria Quimica (ETSEQ) at Universitat Rovira i Virgili aims at becoming an international reference in chemical engineering education and research. The ETSEQ is located in an area that is socially and economically very dynamic, and that is home to one of the most important centers of chemical industry in southern Europe.
The Multidisciplinary Seminar Program is both the seminar series for faculty and researchers in the ETSEQ, and a mandatory class for its graduate students. The Program aims at inviting leading international researchers working on areas that are of interest to faculty and researchers in the School.Learn more

Location: Sala de Graus, ETSEQ
Start time: 12 p.m.
N-Heterocyclic carbenes (NHC) have become a well-established tool in organometallic chemistry.1 Their -donor capacity leads to formation of strong metal-carbon bonds that provide transition metal complexes stable under harsh reaction conditions. These important properties make NHC ligands good candidates for the preparation of catalysts. From the industrial point of view, a stable, highly active and re-usable catalyst, which can easily be separated from reaction products, is very attractive.
Recently, our group described the synthesis and characterization of covalent immobilizated Pd-NHC complexes onto silica, alumina and titania and their applicaton in Suzuki-Miyaura C-C coupling reactions in batch mode as well as under continuous flow conditions.2 The study has been extended to Sonogashira cross-coupling reaction obtaining conversions up to 92 %, superior to any other flow example using NHC as ligands and an aryl bromide as substrate.
New immobilization methodologies and applications for metal-NHC and metal free catalytic systems will be discussed due to our research keeps focused on the development of more environmentaly friendly processes.
