Xanthene-to-Fluorene Skeletal Editing via Oxygen Deletion Mediated by Boron and Aluminium Radicals

Key Points

• The aim is to explore the skeletal editing of diarylethers by selectively removing oxygen atoms through radical-mediated processes.
• Utilized boron and aluminium radicals to perform selective O-deletion.
• Investigated the transformation of xanthene to fluorene frameworks.
• Characterized the new carbon structures formed from the process.
• Successfully demonstrated oxygen deletion from diarylethers.
• Reported the formation of novel carbon frameworks from xanthene to fluorene.
• Achieved the transformation with high selectivity and efficiency.
