This month (June 9-13, 2024) took place the 4th International Conference on Hydrogen Atom Transfer in Castelli romani (Italy), which included a poster session. Dr. Laia Vicens and Dr. Margarida Borrell, postdoc researchers under the supervision of Prof. Miquel Costas, presented a poster titled “Remote Amino Acid Recognition Enables Effective Hydrogen Peroxide at a Manganese Oxidation Catalyst” and “Atropoenantioselective

The tert-butyl group is a common aliphatic motif extensively employed to implement steric congestion and conformational rigidity in organic and organometallic molecules. Because of the combination of a high bond dissociation energy (~ 100 kcal mol-1) and limited accessibility, in the absence of directing groups, neither radical nor organometallic approaches are effective for the chemical
This month the Societat Catalana de Química (SCQ) announced that Dr. Sílvia Simon and Prof. Miquel Costas, researchers at the Institut de Química Computacional i Catàlisi (IQCC) of the UdG, received the Communication Award 2024 (S. Simon) for her communication tasks carried out in any field with the aim of improving the formation of the citizens’ chemical culture and Scientific Excellence Award 2024 (M. Costas) for
The C(sp3)–H bond oxygenation of a variety of cyclopropane containing hydrocarbons with hydrogen peroxide catalyzed by manganese complexes containing aminopyridine tetradentate ligands was carried out. Oxidations were performed in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) and 2,2,2-trifluoroethanol (TFE) using different manganese catalysts and carboxylic acid co-ligands, where steric and electronic properties were systematically modified. Functionalization selectively occurs at the
Last 20th March the Chemistry Department of the University of Girona opened its doors and gives the opportunity to high-school students to know our work through experimental workshops. This provides the secondary school pupils the possibility to get a feel for the research and have real-time chemistry in their hands. Some IQCC members have participated (Prof. Miquel
Precise control of substrate positioning and orientation (its proximity to the reactive unit) is often invoked to rationalize the superior enzymatic reaction rates and selectivities when compared to synthetic models. Artificial nonheme iron (IV) oxo (Fe(IV)=O) complexes react with C(sp3)-H bonds via a biomimetic Hydrogen Atom Transfer/Hydroxyl Rebound mechanism, but rates, site-selectivity and even hydroxyl
8th of March is International Women’s Day. The IQCC has currently a rather favourable balance in gender ratio of staff members, both at the Master level (54%), PhD level (47%), postdocs (17%) and permanent researchers staff (29%). Notably, out of the 4 most recent permanent members, 2 are men and 2 are women, reinforcing one
Marc Garcia-Borràs receives Marcial Moreno-Mañas Award 2023 for young researchers of RSEQ-Cat This week the Real Sociedad Española de Química (RSEQ) announced that Dr. Marc Garcia-Borràs, Ramón y Cajal fellow at the Institut de Química Computacional i Catàlisi (IQCC) of the UdG, received the Marcial Moreno-Mañas Award 2023, for his scientific career of quality and excellence. The Marcial Moreno-Mañas Prize for Young Investigators
Last month (February 25-27, 2024) took place the XIV Spanish-Italian Symposium on Organic Synthesis in Torino (Italy), which included a poster session. Filippo Scarchilli, PhD student under the supervision of Prof. Miquel Costas, presented a poster titled “Highly selective C(sp3)–H bond oxygenation at remote methylenic sites enabled by polarity enhancement”, and won one of the poster prizes.
Yesterday the Italian Chemical Society (SCI) announced that Miquel Costas, full professor at the Institut de Química Computacional i Catàlisi (IQCC) of the UdG, received the Ciamician-González Lectureship 2023 award. This award recognizes his outstanding scientific contributions between Organic Chemistry, Inorganic Chemistry and Applied Catalysis. His studies improve the role and the potential of first-row transition metals in the
