Process for substituting a cyclopentadiene with at least 1 group of the form -RDR'n by deprotonating cyclopentadiene already substituted with at least one other group through reaction with a base, sodium or potassium and then reacting the cyclopentadienyl anion formed with a compound containing a sulphonyl group, the sulphonyl-group-containing compound being a compound according to the formula (R'nD-R-Sul), wherein R is a linking group, R' is a substituent, D is a heteroatom from group 15 or 16 of the Periodic System of the Elements and Sul is a sulphonyl group. |
