Journal ArticleDOI
B19 -: An aromatic wankel motor
TL;DR: Recently, Huang et al. found that the lowest energy form of B19 (1) is a beautiful ring structure with two planar paromatic systems nested inside one another.
Journal ArticleDOI
Nucleus-independent chemical shift (NICS) profiles in a series of monocyclic planar inorganic compounds
TL;DR: In this article, a series of monocyclic planar inorganic compounds have been optimized at the B3LYP/6-311+G * level, and the NICS profiles calculated in the perpendicular direction of each ring show that the analyzed compounds can be classified in three groups according to their aromatic, non-aromatic or antiaromatic character.
Journal ArticleDOI
Metal-free binding and coupling of carbon monoxide at a boron–boron triple bond

TL;DR: In this work, CO was added to a boron-boron triple bond at room temperature and atmospheric pressure, resulting in a compound into which four equivalents of CO are incorporated: a flat, bicyclic, bis(boralactone).
Journal ArticleDOI
An isolable radical anion based on the borole framework.
Holger Braunschweig,Vladimir Dyakonov,J. Oscar C. Jiménez-Halla,Katharina Kraft,Ivo Krummenacher,Krzysztof Radacki,Andreas Sperlich,Johannes Wahler +7 more
TL;DR: The group set out to isolate and characterize a stable borol radical anion, a class of antiaromatic compounds with interesting chemical and photophysical properties that are well-known for their ability to accept two electrons with formation of an aromatic borole dianion.
Journal ArticleDOI
A Critical Assessment of the Performance of Magnetic and Electronic Indices of Aromaticity
TL;DR: Evaluating the aromaticity of two series of all-metal and semimetal clusters with predictable aromaticity trends by means of NICS and MCI shows that the expected trends are generally better reproduced by MCI than NICS.
