Olefin metathesis seems to be a complex chemical reaction, but if we say that leads to the formation of polymers, i.e. plastics, it is really simple and it is valid in any item that currently we have in our hands. This field of olefin metathesis is mature, after the Nobel Prize in 2005 of Chauvin,

The formidable challenges of controlling site-selectivity, enantioselectivity and product chemoselectivity, make asymmetric C-H oxidation a generally unsolved problem for non-enzymatic systems. Discrimination between the two enantiotopic C-H bonds of an unactivated methylenic group is particularly demanding and so far unprecedented, given the similarity between their environments and the facile overoxidation of the initially formed hydroxylation
Next Tuesday (14th of January, 10.30h, Aula Magna, Faultat de Ciències) will take place the defense of the doctoral thesis of Steven Roldán titled “Computational Mechanistic Studies of C-H and C-X Activated Organometallic Species with First-row Transition Metals” supervised by Dr Xavi Ribas and Dr. Josep M. Luis from IQCC We wish him good luck
In situ oxidation of the GaI compound NacNacGa by either N2O or pyridine oxide results in the generation of a labile monomeric oxide, NacNacGa(O), which can easily cleave the C?H bonds of aliphatic and aromatic substrates featuring good donor sites. The products of this reaction are gallium organyl hydroxides. DFT calculations show that these reactions
Next Thursday, 19 december, 10.30-13.15h, will take place the Christmas edition of the IQCC Forum, a quarterly meeting-place where high-quality science will be discussed. The IQCC Forum provides the opportunity for young researchers (and more advanced researchers) to present their work to a wide audience. This will lead to better knowledge of the work that is being
The burning of fossil fuels is causing a global climatic emergency. In order to solve this crisis, it is very important to improve the efficiency of the production of renewable energies by transforming carbon dioxide into carbon-based fuels. Recently, IQCC researcher Josep M. Luis in collaboration with ICIQ’s Lloret group, determined the mechanism and bottlenecks
Previously, an unexpected Co-catalysed remote C-H nitration of 8-aminoquinolinamide compounds was developed. This report provided a novel reactivity for Co and was assumed to proceed through the mechanistic pathway already known for analogous Cu-catalysed remote couplings of the same substrates. In order to shed light into this intriguing, and previously unobserved reactivity for Co, a
Isomer-pure poly-functionalized fullerenes are required to boost the development of fullerene chemistry in all fields. On a general basis, multi-adduct mixtures with uncontrolled regioselectivity are obtained, and the use of chromatographic purification is prohibitively costly and time consuming, especially in the production of solar cells. Single-isomer poly-functionalized fullerenes are only accessible via stoichiometric, multistep paths
Today Sílvia Osuna received the Premio Lilly Joven de Investigación 2019 at the headquarters of Lilly in Madrid, where she also delivered her award-ceremony talk “Computational enzyme evolution”. She has won the award, as already announced earlier this year, for her outstanding scientific career on enzyme design, fullerenes, and carbon materials. The Lilly Prize for Young Investigators
Prof. Marcel Swart, director of the IQCC since 2015, was recently elected as member of Academia Europaea and received yesterday the corresponding decorations. The Academia Europaea is a pan-European Academy founded in 1988 and is composed of individual scientists and scholars from all disciplines, who are experts and leaders in their own subject areas as
