Inorganic Benzene Valence Isomers.

Area of Science:

• Inorganic chemistry
• Organic chemistry
• Computational chemistry

Background:

• Benzene (CH)6 is the most stable of over 200 proposed C6H6 isomers.
• Three benzene valence isomers (CR)6—prismane, Dewar benzene, and benzvalene—have been synthesized.
• Inorganic analogues of benzene and its isomers offer unique structural and electronic properties.

Purpose of the Study:

• To review the synthesis and characterization of inorganic benzene and its valence isomers.
• To discuss the stability and chemical properties of these inorganic analogues.
• To highlight the growing field of inorganic benzene chemistry.

Main Methods:

• Literature review of experimentally developed inorganic benzene analogues.
• Analysis of synthesis strategies for these compounds.
• Discussion of characterization techniques and stability assessments.

Main Results:

• Over 30 examples of inorganic benzene and its valence isomers have been synthesized and characterized.
• These compounds exhibit distinct structural and electronic features compared to their organic counterparts.
• Various synthetic routes have been established for accessing these inorganic systems.

Conclusions:

• Inorganic benzene and its isomers represent a diverse and expanding area of chemical research.
• The incorporation of heteroatoms provides access to novel molecular architectures with tunable properties.
• Further investigation into their stability and reactivity is warranted for potential applications.
