Aromatic chloroosmacyclopentatrienes

open access: yesNational Science Review, 2022
ABSTRACT Aromatic metallacycles are of considerable current interest. Reported aromatic metallacycles are mainly those with carbon, nitrogen, oxygen and sulfur. In this work, we report the synthesis and characterization of aromatic chloroosmacyclopentatrienes, which represent the first structurally confirmed metallaaromatic with a ...

Hydrogenated polycyclic aromatic hydrocarbons: isomerism and aromaticity

open access: yesPhysical Chemistry Chemical Physics, 2020
A simple model based on adjacency matrices is introduced to study the stability of hydrogenated polycyclic aromatic hydrocarbons. Aromaticity governs their relative stability having the most stable isomers the higher number of non-hydrogenated rings.

Arylamine Synthesis Enabled by a Photocatalytic Skeletal-Rearrangement Dehydrogenative Aromatization Strategy

open access: yes, 2023
Construction of aromatic compounds from non-aromatic compounds with skeletal edit are appealing yet challenging in organic chemistry. Herein, we report an approach for the synthesis of site-selective substituted arylamines via photocatalyzed C-N coupling/

Synthesis of Heteroaromatic Compounds by Oxidative Aromatization Using an Activated Carbon/Molecular Oxygen System

open access: yesMolecules, 2009
A variety of heteroaromatic compounds, such as substituted pyridines, pyrazoles, indoles, 2-substituted imidazoles, 2-substituted imidazoles, 2-arylbenzazoles and pyrimidin-2(1H)-ones are synthesized by oxidative aromatization using the activated carbon ...

Aromatic Borozene [PDF]

open access: yesNanoscale Research Letters, 2009
Abstract Based on our comprehensive theoretical investigation and known experimental results for small boron clusters, we predict the existence of a novel aromatic inorganic molecule, B12H6. This molecule, which we refer to as borozene, has remarkably similar properties to the well-known benzene.
