Process for the preparation of a substituted cyclopentadiene compound, comprising the reaction of a halide of a substituting compound in a mixture of the cyclopentadiene compound and an aqueous solution of a base in the presence of a phase transfer catalyst, wherein during the reaction the quantity of base relative to the cyclopentadiene compound is at any moment between 5 and 30 mol/mol.
Méthode de préparation d'un dérivé de substitution du cyclopentadiène, consistant à faire réagir un halogénure d'un composé substituant dans un mélange du dérivé de cyclopentadiène et d'une solution aqueuse d'une base, en présence d'un catalyseur de transfert phasique, où lors de la réaction le rapport molaire base/dérivé de cyclopentadiène se situe à n'importe quel moment entre 5 et 30.
