SYNTHESIS OF AN AMINE-CONTAINING CYCLOPENTADIENE

摘要

Process for the substitution of a cyclopentadiene with at least one amine-containing substituent by deprotonating a cyclopentadiene compound by reaction with a base, sodium or potassium and then reacting the resulting cyclopendadienyl anion with a compound containing an amine group, wherein the compound containing the amine group is a compound according to the formula (R'2N-R-Sul), in which R is a bonding group, R' is a substituent, N is a nitrogen atom and Sul is a sulphonyl group, which compound has been formed in situ by a reaction of an amino alcohol compound with successively a base and a sulphonyl halide.
