f-Block Phospholyl and Arsolyl Chemistry.

Area of Science:

• Organometallic Chemistry
• Inorganic Chemistry
• f-block elements

Background:

• Phospholyl and arsolyl ligands are heavier p-block analogues of cyclopentadienyl ligands.
• Their f-block chemistry is less developed compared to cyclopentadienyls.
• Recent interest in f-block solution chemistry motivates a review of these systems.

Purpose of the Study:

• To review the syntheses of structurally characterized lanthanide and actinide phospholyl and arsolyl complexes.
• To cover benzannulated derivatives and group 3 complexes.
• To review the physicochemical properties of these complexes and encourage further research.

Main Methods:

• Literature review of syntheses and characterization of f-block phospholyl and arsolyl complexes.
• Compilation of structurally characterized examples.
• Analysis of reported physicochemical properties.

Main Results:

• Comprehensive coverage of known lanthanide, actinide, and group 3 phospholyl and arsolyl complexes.
• Inclusion of benzannulated derivatives.
• Summary of their diverse physicochemical properties.

Conclusions:

• The field of f-block phospholyl and arsolyl chemistry is underexplored but shows promise.
• These ligands offer unique properties compared to traditional cyclopentadienyls.
• Further research is encouraged to expand this area of organometallic chemistry.
