Enzymes exist as ensembles of conformations that are important for function. Tuning these populations of conformational states through mutation enables evolution toward novel activity. In the paper published in ACS Catalysis, Adrian Romero-Rivera, Marc Garcia-Borràs, and Sílvia Osuna describe a “shortest path map” tool based on inter-residue correlations along microsecond-scale MD simulations that is able

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
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”
Today a paper was published by Agustí Lledó, Anna Roglans and Miquel Solà on “A Computational Study of the Intermolecular [2+2+2] Cycloaddition of Acetylene and C60 Catalyzed by Wilkinson’s Catalyst”. It is accompanied by the Cover picture. A. Artigas, A. Lledó, A. Pla-Quintana, A. Roglans, and M. Solà “A Computational Study of the Intermolecular [2+2+2]
Yago García-Rodeja and Israel Fernández (Univ. Complutense de Madrid), Miquel Solà from the Institute of Computational Chemistry and Catalysis (IQCC) and F. Matthias Bickelhaupt from the Department of Theoretical Chemistry and Amsterdam Center for Multiscale Modeling (ACMM) in the Vrije Universiteit Amsterdam (usual collaborator of the IQCC) have studied the influence of the encapsulation of
Today a paper was published by Abril Castro, Marcel Swart and Célia Fonseca Guerra on the “Influence of Substituents and Environment on NMR Shielding Constants of Supramolecular Complexes based on A-T and A-U Base Pairs” in Phys. Chem. Chem. Phys. 2017, 19, 13496-13502: In the present study, we have theoretically analyzed supramolecular complexes based on the Watson–Crick A–T and
Density functional theory (DFT) calculations have been used to describe the first turnover of an olefin metathesis reaction calling for a new in silico family of homogenous Ru-based catalysts bearing a phosphine–phosphonium ylide ligand, with ethylene as a substrate. Equal to conventional Ru-based catalysts bearing an N-heterocyclic carbene (NHC) ligand, the activation of these congeners
Today a new paper was published in Adv. Synth. Catal. on enantioselective cascade cyclopropanation reactions catalyzed by rhodium(I), through the asymmetric synthesis of vinylcyclopropanes. Ò. Torres, A. Roglans, and A. Pla-Quintana “An Enantioselective Cascade Cyclopropanation Reaction Catalyzed by Rhodium(I): Asymmetric Synthesis of Vinylcyclopropanes” Adv. Synth. Catal. 2016, 358, 3512-3516 DOI: 10.1002/adsc.201600789 It also featured on the
Achieving high selectivity among different nucleophiles has been a hard nut to crack in Cu-catalyzed Ullmann C–O and C–N couplings. The cover art of the Journal of Organic Chemistry illustrates that a precise selection of the auxiliary ligand is the key to achieving orthogonal selectivities in the arylation of mixed nucleophiles. In a similar manner,
