Abstract
Aluminum cyclopentadienyl compounds can be used to synthesize a variety of organic molecules containing the cyclopentadiene group, e.g., substituted cyclopentadiene compounds, polymer molecules with cyclopentadiene pendant groups, and polymer molecules with cyclopentadiene terminal groups.
