Aryllithium added with 6,6-dialkylfulvenes at exocyclic double bond to give bulkier substituted cyclopentadienyl anions with chiral or achiral carbon. Complexed by hafnium chloride nineteen bulkier substituted hafnocene dichlorides were synthesized, and those 1H NMR will be discussed. The structure of [(CH3)2C(C6H4-p-CH3)C5H4]2HfCl2 has been determine by x-ray diffraction.
