Close O-O contacts make me redder. The tetrafurylethene AIE luminogen has a strong red morphochromism going from the aggregate to the crystalline phase (27 nm). In this joint study with the group of B.-Z. Tang in Honk-Kong University of Science and Technology, which started with the visit of L. Viglianti in 2018, Lluís Blancafort and

Many drugs used for the treatment of diseases present chiral properties. In this study we aimed to produce an optically pure stereoisomer that is a key intermediate for the production of steroidal medicines such as levonorgestrel or gestodene. The targeted stereoisomer was the (13R, 17S)-methyl secol, which can be produced by the asymmetric reduction of
Nickel-catalyzed C-F activations enabled chemo-divergent C-C formation with alkynes by chelation assistance. The judicious choice of the al-kynes electronic properties allowed the selective synthesis of double-insertion aromatic homologation or alkyne mono-annulation products by C-F/C-H activation. Based on the unambiguous crystallographic characterization of an unprecedented 9-membered nickelocyclic intermediate and extensive DFT studies, a plausible mechanistic rationale
Tomorrow (3rd of October, 16h, Sala d’actes, edifice LEAR, Aulari Comú) will take place the Autumn edition of the IQCC Forum, a quarterly meeting-place where high-quality science will be discussed. The IQCC Forum gives the opportunity for PhD and postdoc members of the IQCC to present their work to a wide audience. This will lead
Nickel complexes have been widely employed as catalysts in C–C and C–heteroatom bond formation reactions. While Ni(0), Ni(I), and Ni(II) intermediates are most relevant in these transformations, recently Ni(III) and Ni(IV) species have also been proposed to play a role in catalysis. Reported herein is the synthesis, detailed characterization, and reactivity of a series of
The development of artificial synthetic receptors that imitate the binding site of enzymes and other proteins is a challenging task. In particular, reproducing the innate flexibility of proteinogenic receptors is particularly difficult, although it is an essential feature for functions such as enzymatic catalysis. Now, researchers at IQCC have developed a novel synthetic receptor that
A few weeks ago a new author database of top scientists was published by a team of four researchers from the USA and Netherlands, which took data from Elsevier’s Scopus database to provide standardized information on citations and several indices. Two approaches were taken, one long-term (career) impact and one short-term impact where output from
This morning at the IQCC Council meeting we approved the recognition of the following three researchers as Principal Investigator of the institute: Ferran Feixas Josep Maria Luis Pedro Salvador In the coming days this new situation will be reflected on the website. Congratulations, we’re looking forward to hearing a lot from you!
Next Friday (27th of September, 11.00h, Aula Magna, Facultat de Ciències) will take place the defense of the doctoral thesis of Mònica Rodriguez titled “First row transition metal carbenes: from supporting ligands to organic reactive fragments” supervised by Dr Miquel Costas and Dr. Alberto Hernán-Gómez from IQCC. We wish her good luck and all the
Dr. Jun Wang has recently become a new member of the Institute of Computational Chemistry and Catalysis (IQCC) with a Marie Sklodowska-Curie IF fellowship. Dr. Wang did his PhD in Shandong University on studies on the related properties of negative dissociation energy state associated with the DNA hole migration under the supervision of Prof. Yuxiang
