Title
(EN) PROCESS FOR THE PREPARATION OF ARYL AND ARALKYL MAGNESIUM HALIDES
(FR) PROCEDE DE PREPARATION D'HALOGENURES DE MAGNESIUM ARYLE ET ARALKYLE
Abstract
(EN) Process for the preparation of compounds of the formula (I): Y-Mg-X wherein Y is an optionally substituted phenyl or benzyl, and X is a halogen, by reaction of a compound of the formula (II): Y-X wherein Y and X have the meanings given above, with magnesium in a solvent, characterised in that the solvent is an acetal of formula (III), wherein R1 and R2 are independently alkyl having from 1 to 6 carbon atoms or when taken together form a dioxolane ring, and R3 is hydrogen or alkyl having from 1 to 6 carbon atoms.
(FR) La présente invention se rapporte à un procédé de préparation de composés de la formule (I): Y-Mg-X dans laquelle Y représente phényle ou benzyle éventuellement substitué et X représente halogène, consistant en la réaction d'un composé de la formule (II): Y-X dans laquelle Y et X ont les significations données ci-dessus, avec du magnésium dans un solvant, et caractérisé en ce que le solvant représente un acétale de la formule (III) dans laquelle R1 et R2 représentent indépendamment alkyle possédant de 1 à 6 atomes de carbone ou bien réunis forment un anneau de dioxolane, et R3 représente hydrogène ou alkyle possédant de 1 à 6 atomes de carbone.
