Abstract
La présente invention a pour objet un procédé de préparation d'un alcool à partir d'un composé halogénoaromatique et d'un aldéhyde conduisant à un composé α-hydroxyalkylaromatique.Le procédé de préparation d'un composé α-hydroxyalkylaromatique selon l'invention est caractérisé par le fait qu'il comprend une étape de préparation d'un composé organozincique aromatique par réaction d'un halogénure aromatique avec du zinc, en présence d'un sel de cobalt, puis la réaction sans séparation dudit organozincique obtenu avec un aldéhyde éventuellement en présence d'un acide de Lewis.
