This study synthesizes novel aromatic rhenabenzynes from alkynols and a rhenium hydride complex. These compounds exhibit aromatic character confirmed by spectroscopic and computational analyses.
Area of Science:
- Organometallic Chemistry
- Rhenium Chemistry
- Aromaticity Studies
Background:
- Organometallic complexes are crucial in catalysis and materials science.
- Understanding the aromaticity of novel inorganic compounds expands chemical principles.
Purpose of the Study:
- To synthesize and characterize new rhenium-containing compounds.
- To investigate the aromatic nature of novel rhenabenzynes.
Main Methods:
- Reaction of [ReH(5)(PMe(2)Ph)(3)] with substituted alkynols and HCl.
- Grignard reactions and fluoride-induced desilylation.
- NMR spectroscopy, X-ray crystallography, aromatic stabilization energy (ASE) calculations, and nucleus-independent chemical-shift (NICS) values.
Main Results:
- Synthesis of vinylcarbyne complexes and their subsequent transformation.
- Formation of bicyclic intermediates and final rhenabenzynes.
- Spectroscopic and computational data indicating aromatic character in the synthesized rhenabenzynes.
Conclusions:
- Novel rhenabenzynes were successfully synthesized and characterized.
- The synthesized rhenabenzynes possess significant aromatic character.
- This work contributes to the understanding of aromaticity in organometallic compounds.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
