Disclosing Chemical Bonds

What is a chemical bond? The chemical bond is a central concept for describing and predicting molecular structure and reactivity. Since a chemical bond does not have an operator in quantum mechanics, there is no exclusive approach to describe it unequivocally. A fundamental approach towards understanding its properties consists in classifying the electron-pair interactions between

Mutational analysis of LinD suggests transformations are catalyzed using non-covalent mechanisms

The interconversion of non-activated alkenes and alcohols, catalysed by (de)hydratases, has great potential in biotechnology for the generation of fine and bulk chemicals. LinD is a cofactor-independent enzyme that catalyses the reversible (de)hydration of the tertiary alcohol (S)-linalool to the triene b-myrcene, and also its isomerization to the primary alcohol geraniol. In this collaboration project

Predicting distal active site mutations in computational enzyme design

Many computational enzyme design approaches have been developed in recent years that focus on a reduced set of key enzymatic features. Initial protocols mostly focused on the chemical steps(s) through transition state stabilization, whereas most recent approaches exploit the enzyme conformational dynamics often crucial for substrate binding, product release and allosteric regulation. The detailed evaluation

Unveiling the mechanism of the iodane-guided ortho C-H allylation

A metal-free C-H allylation strategy is described to access diverse functionalized ortho-allyl-iodoarenes. The method employs hypervalent (diacetoxy)iodoarenes and proceeds through the iodane-guided “iodonio-Claisen” allyl transfer. The use of allylsilanes bearing electron-withdrawing functional groups unlocks the functionalization of a broad range of substrates, including electron-neutral and electron-poor rings. The resulting ortho-allylated iodoarenes are versatile building blocks, with examples

Miquel Costas elected as new Fellow of the Royal Society of Chemistry

Miquel Costas has recently been selected as a Fellow of the Royal Society of Chemistry (RSC). This scientific society, founded in 1980, aims to promote the understanding and advancement of the chemical sciences. Although the vast majority of more than 54,000 members of the association are British, this is also open to researchers from around

Marc Garcia-Borràs selected as one of the six finalists of the European Young Chemists Award

The aim of the European Young Chemists’ Award (EYCA) is to showcase and recognize the excellent research being carried out by young scientists working in the chemical sciences. In particular the award is intended to honor and encourage younger chemists whose current research displays a high level of excellence and distinction. It seeks to recognize and reward younger

Dynamic reconstruction of fullerene encapsulation into an adaptable supramolecular nanocapsule

The dynamic adaptability of a supramolecular tetragonal prismatic nanocapsule in the selective separation of fullerenes and endohedral metallofullerenes (EMFs) remained unexplored. Therefore, the essential molecular details of the fullerene recognition and binding process into the coordination capsule and the origins of fullerene selectivity remained elusive. In this work, the key steps of fullerene recognition and

Enzyme powered micro/nanomotors

Enzyme powered micro/nanomotors have great potential applications in various areas, especially in the biomedical and environmental fields. To efficiently reach those applications, it is necessary to understand the fundamental aspects affecting the motion dynamics. In this collaboration project between IBEC (Prof. Sanchez), UCM (Dr. Filice), and IQCC (M. Estévez, Dr. Iglesias-Fernández, Prof. Osuna), we explored
