Chalcogen Bonding Catalysis: Tellurium, the Last Frontier?

Area of Science:

• Supramolecular Chemistry
• Catalysis
• Materials Science

Background:

• Chalcogen bonding (ChB) is a non-covalent interaction involving chalcogen atoms acting as Lewis acids.
• This interaction, similar to halogen bonding, enables precise structural organization in solid and solution states.
• ChB is recognized as a novel activation mode in catalysis, with growing applications.

Purpose of the Study:

• To review the Lewis acid properties of tellurium-based derivatives in solution.
• To summarize the current state of applications of tellurium-based chalcogen bonding in catalysis.

Main Methods:

• Literature review focusing on chalcogen bonding.
• Analysis of Lewis acid properties of tellurium compounds.
• Summary of catalytic applications of tellurium-based ChB.

Main Results:

• Tellurium-based chalcogen bonding catalysts exhibit significant Lewis acid characteristics.
• These tellurium derivatives often outperform lighter chalcogen (sulfur, selenium) counterparts in catalysis.
• Numerous examples demonstrate the effectiveness of ChB in catalytic processes.

Conclusions:

• Tellurium-based compounds are highly effective as Lewis acids in chalcogen bonding catalysis.
• The unique properties of tellurium-based ChB catalysts warrant further investigation and application.
• Chalcogen bonding, particularly with tellurium, represents a promising frontier in catalytic science.
