The Journal of the American Chemical Society (JACS) features on its front cover the recently published article “Too Persistent to Give Up: Aromaticity in Boron Clusters Survives Radical Structural Changes”. The work has been carried out by Francesc Teixidor, Clara Viñas, and Ines Bennour of the Institute of Materials Science of Barcelona (ICMAB-CSIC), Jordi Poater at

The incarceration of o?benzyne and 27 other guest molecules within hemicarcerand 1, as reported experimentally by Warmuth, and Cram and co?workers, has been studied by density functional theory (DFT). The 1H-NMR chemical shifts, rotational mobility, and conformational preference of the guests within the supramolecular cage were determined, which showed intriguing correlations of the chemical shifts
We report here a computational study on a series of FeII, FeIII, and FeIV hydroxo/oxoiron complexes with a broad palette of ligands. We are interested in assessing the robustness of widely used density functionals for their prediction and description of structures and spin states for the examined oxoiron complexes. We have used a variety of density
A novel methodology to transform bisallenes into a variety of polycyclic derivatives employing rhodium(I) catalysis has been developed. This transformation encompasses an intramolecular Rh-catalyzed cycloisomerization of bisallenes 1 to deliver a reactive cycloheptadiene, which concomitantly undergoes a regioselective [4 + 2] cycloaddition with alkenes. A complete mechanistic study of this transformation has been undertaken including
We report a combined experimental–theoretical study on the 31P NMR chemical shift for a number of trans-platinum(II) complexes. Validity and reliability of the 31P NMR chemical shift calculations are examined by comparing with the experimental data. A successful computational protocol for the accurate prediction of the 31P NMR chemical shifts was established for trans-[PtCl2(dma)PPh3] (dma
Although the unusual structural, magnetic, electronic, and spin characteristics of manganocene has intrigued scientists for decades, a unified explanation and rationalization of its properties has not yet been provided. Results obtained by Multideterminantal Density Functional Theory (MD-DFT), Energy Decomposition Analysis (EDA), and Intrinsic Distortion Path (IDP) methodologies indicate how this uniqueness can be traced back
We have derived a new set of magic numbers for metallic clusters whose last energy level of valence electrons is half-filled with same-spin electrons in the electronic structure of the jellium model. These numbers may become a powerful tool for finding stable high-spin molecules. The 2N2 + 2N + 1 with S = N +
The synthesis and characterization of a covalent all?fullerene C60?Lu3N@Ih?C80 electron donor–acceptor conjugate has been realized by sequential 1,3?dipolar cycloaddition reactions of azomethine ylides on Lu3N@Ih?C80 and C60. To the best of our knowledge, this is the first time that two fullerenes behaving as both electron donor (Lu3N@Ih?C80) and acceptor (C60) are forming an electroactive dumbbell.
A group of chemists from the Euskal Herriko Unibertsitatea (UPV/EHU) and the Donostia International Physics Center (DIPC) lead by Dr. Eduard Matito (ex-member IQCC) together with the IQCC members Mauricio Rodríguez-Mayorga (now in ETH Zurich, Switzerland) and Dr. Miquel Solà, have studied the Coulomb hole of Ne from highly-accurate CISD wave functions obtained from optimized even-tempered basis sets.
Albert Artigas, Anna Pla-Quintana, Agustí Lledó, Anna Roglans, and Miquel Solà, members of the DiMoCat group of the Institute of Computational Chemistry and Catalysis, have developed a synthetic method to generate open-cage fullerenes in a catalytic process. The Rh(I) catalyst employed is able to promote not only the [2+2+2] cycloaddition reaction but also the subsequent
