Documentary Picture a Scientist at the UdG

Last Friday, the IQCC organized a meeting to show the documentary Picture a Scientist and a round table with Assumpció Vila Simon, Anna Pla-Boix and Carme Font-Paz to highlight gender inequality in science during the Science Week. The film tells the stories of several prominent female researchers and brings to light the barriers that they encountered, including cases of discrimination

Science Week – Diada de Sant Albert at IQCC and Science Faculty UdG

Every year in November, the IQCC is organizing together with the Scientific Culture and Digital Communication (C4D) unit of the UdG some activities for Science Week with the aim to bring our science closer to the Girona general public. Last Friday, November 18, 2022, the Diada de Sant Albert took place at Science Faculty of UdG. The

Third IndustryQCC Forum

Last Thursday, the IQCC organized the third edition of the IndustryQCC Forum with four national and international companies (Repsol, Eli Lilly, AstraZeneca and Pfizer) during the Science Week. The IndustryQCC Forums provide young (and more advanced) researchers of IQCC the opportunity to get to know the research carried out in (bio)chemical industry in different parts of

Intramolecular Interception of the Remote Position of Vinylcarbene Silver Complex Intermediates by C(sp3)-H Bond Insertion

The trapping of the elusive vinylogous position of a vinyl carbene with an aliphatic Csp3-H bond has been achieved for the first time during a silver-catalyzed carbene/alkyne metathesis (CAM) process. A Tpx-containing silver complex first promotes the generation of a donor-acceptor silver carbene which triggers CAM, generating a subsequent donor-donor vinyl silver carbene species, which

Carboxylic Acid Directed gamma-Lactonization of Unactivated Primary C–H Bonds Catalyzed by Mn Complexes: Application to Stereoselective Natural Product Diversification

Reactions that enable selective functionalization of strong aliphatic C–H bonds open new synthetic paths to rapidly increase molecular complexity and expand chemical space. Particularly valuable are reactions where site-selectivity can be directed toward a specific C–H bond by catalyst control. Herein we describe the catalytic site- and stereoselective ?-lactonization of unactivated primary C–H bonds in

Characterization of a Ferryl Flip in Electronically Tuned Nonheme Complexes. Consequences in Hydrogen Atom Transfer Reactivity

Two oxoiron(IV) isomers ( R2a and R2b) of general formula [FeIV(O)(RPyNMe3)(CH3CN)]2+ are obtained by reaction of their iron(II) precursor with NBu4IO4. The two isomers differ in the position of the oxo ligand, cis and trans to the pyridine donor. The mechanism of isomerization between R2a and R2b has been determined by kinetic and computational analyses
