C-F→Ln/An interactions in synthetic f-element chemistry

Area of Science:

• Coordination chemistry
• Organometallic chemistry
• Inorganic chemistry

Background:

• Coordination of C-F moieties to electrophilic metal cations, particularly f-elements (lanthanides/actinides), has gained prominence.
• These C-F→Ln/An interactions are observable in both solid and solution states.

Purpose of the Study:

• To review the role of C-F→Ln/An interactions in f-element chemistry.
• To examine their influence on C-F bond activation and catalysis.
• To discuss their impact on coordination compound geometry and electronic properties.

Main Methods:

• Literature review and analysis of existing studies on C-F→Ln/An interactions.
• Examination of binding energies and displacement phenomena.
• Discussion of C-F bond cleavage mechanisms (homolytic/heterolytic).

Main Results:

• C-F→Ln/An interactions are prevalent and can persist in solution.
• Their binding energies facilitate metal center exposure, crucial for cationic polymerization catalysts.
• These interactions are fundamental to C-F bond activation pathways.

Conclusions:

• C-F→Ln/An coordination plays a significant role in f-element chemistry.
• Understanding these interactions is vital for designing new catalysts and C-F bond activation strategies.
• Further investigation into their geometric and electronic effects is warranted.
