Site-selective C-H functionalization of aliphatic alkyl chains is a longstanding challenge in oxidation catalysis, given the comparable relative reactivity of the different methylenes. A supramolecular, bioinspired approach is described to address this challenge. A Mn complex able to catalyze C(sp3)-H hydroxylation with H2O2 is equipped with 18-benzocrown-6 ether receptors that bind ammonium substrates via hydrogen bonding.
A few weeks ago for the first time an IQCC-related paper appeared in Nature, with the publication of “Discovery of a selective catalytic p300/CBP inhibitor that targets lineage-specific tumours”, with Maricel Torrent as one of the authors. Maricel defended her PhD thesis “On the mechanisms of Transition-Metal Catalyzed Model Reactions of Industrial and Synthetic Importance:
A group of chemists from the Universidad Complutense de Madrid lead by Prof. Nazario Martín and from the University of Southampton lead by Prof. Richard J. Whitby together with the IQCC members Sílvia Osuna, Miquel Solà, and Marc Garcia-Borràs (ex-member of the IQCC, now in UCLA) have reported the first chemical modification on the endohedral
Today Teresa Corona and Anna Company reported in Anales de Química on metal-imido species, including the Cover picture by them. The corresponding paper (in Spanish) can be found here: Teresa Corona Prieto, Anna Company Casadevall “Especies metal-imido de alta valencia con metales tardíos de la primera serie de transición” An. Quím. 2017, 162-169
This October, our former member of IQCC Joan Serrano was awarded the Premi Extraordinari for the best PhD thesis in 2016 from the University of Girona. Last year, he defended with success his PhD thesis on “Bioinspired copper and nonheme iron models for oxygen activation: unprecedented reactivities”, supervised by Anna Company and Miquel Costas. Now, Joan is continuing his
Today Prof. Marcel Swart received a special award from the Serbian Chemical Society for his continuous support for advancing chemical sciences in Serbia. The award was given in Belgrade at the Annual Meeting of the Serbian Chemical Society in honor of 120 years of the Society. The prize was handed out by the division manager
Today a new paper was published in Angew. Chem. Int. Ed. on the oxidation catalysis of a highly reactive oxoiron(IV) complex. I. Monte?Pérez, X. Engelmann, Y. Lee, M. Yoo, E. Kumaran, E.R. Farquhar, E. Bill, J. England, W. Nam, M. Swart, and K. Ray “A Highly Reactive Oxoiron(IV) Complex Supported by a Bioinspired N3 O Macrocyclic Ligand”
The sluggish oxidants, [FeIV(O)(TMC)(CH3CN)] 2+ (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) and [FeIV(O)(d12-TMCN)(OTf)] + (3d; d12-TMCN = 1,4,7,11-tetra-d3-methyl-1,4,7,11-tetraazacyclotetradecane), are transformed into a highly reactive oxidant, [FeIV(O)(TMCO)(OTf)] + (1; TMCO = 4,8,12-trimethyl-1-oxa-4,8,12-triazacyclotetradecane), upon replacement of a -NMe donor in the TMC and TMCN ligands by an O-atom. A rate enhancement of 5 – 6 orders of magnitude in both
Today for the first time an IQCC-related paper appeared in Science, with the publication of “Angular momentum–induced delays in solid-state photoemission enhanced by intra-atomic interactions”, with Miquel Torrent-Sucarrat as one of the authors. Miquel defended his PhD thesis “Desenvolupament, implementació i aplicació de noves metodologies per a l’estudi de la reactivitat química i de les
