Today the Human Frontier Science Program has announced the list of the awardees in the latest 2020 call, among which featured our Sílvia Osuna (ICREA) with a research project on “the evolution of conformational and kinetic ensembles during functional transitions” (RGP0054/2020). The team of the project is composed by Prof. Tokuriki (grant coordinator, University of

Site-selective and product chemoselective aliphatic C–H bond oxidation of 1,2-diols and of polyhydroxylated substrates using iron and manganese catalysts and hydrogen peroxide as terminal oxidant is described. The reaction capitalizes on the use of fluorinated alcohol solvents such as 2,2,2-trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), which exert a strong polarity reversal in the hydroxyl moieties of
In soluble methane monooxygenase enzymes (sMMO) dioxygen (O2) is activated at a diiron(II) center to form an oxodiiron(IV) intermediate Q that performs the challenging oxidation of methane to methanol. An analogous mechanism of O2 activation at mono- or di-nuclear iron centres is rare in the synthetic chemistry. Herein, we report a mononuclear non-heme iron(II)-cyclam complex
Exploration and comprehension of chemical bonding is one of the central tasks in chemistry. Here, a non-covalent interaction, a nido-cage···? bond, is discovered in a collaborative work between Deshuang Du and Prof. Yan from Nanjing University and Prof. Jordi Poater at the University of Barcelona (ex-IQCC) and Prof. Miquel Solà of IQCC (Univ. Girona). The
The IQCC was created in 1993 (as IQC, focusing only on computational chemistry), and was joined in 2013 by two experimental groups (QBIS, METSO) because of long-standing collaborations and mutual interests. Right now, in this vibrant community of highly motivated researchers that are working on predictive catalysis both at lab benches and through molecular modelling, we
Today ICREA announced the list of winners of the ICREA Acadèmia awards 2019, among which are three (!!!) names from the University of Girona: Sebastià Puig (Engineering), Anna Company and Albert Poater (both IQCC and Chemistry). Congratulations to all three!
Today (11th of Febraury) is the International day of Women and Girls in Science. In order to celebrate this day, three of our IQCC women (Dr. Sílvia Osuna @silviaosu, Dr. Sílvia Simon @SilviaSimonR and Carla Calvó @ccalvotusell) will give lectures at Schools. Furthermore, Dr. Sílvia Osuna will participate in a round-table discussion at the “Científiques Catalanes 2.0”
On February 1st, Dr. Marc Garcia-Borràs started his new Beatriu de Pinós project (MSCA COFUND) entitled “Computational characterization of enzymatic reactive intermediates for the discovery and design of new biocatalytic activities”. This 3-year project will allow Dr. Garcia-Borràs to work as an independent researcher at the Institute of Computational Chemistry and Catalysis (IQCC) and the
Soluble methane monooxygenase (sMMO) carries out methane oxidation at 4 °C and under ambient pressure in a catalytic cycle involving the formation of a peroxodiiron(III) intermediate (P) from the oxygenation of the diiron(II) enzyme and its subsequent conversion to Q, the diiron(IV) oxidant that hydroxylates methane. Synthetic diiron(IV) complexes that can serve as models for
In search of green sustainable chemistry there are different objectives to move forward in our quest to improve the world surrounding us. Here, in this contribution a collaborative study between the experimental group of Prof. Jean Luc Renaud (Univ. Normandy, France) and Dr. Albert Poater (IQCC) for the complementary computational part is reported. They have been able to achieve not only
