Process for the preparation of compounds of formula (I): Y--Mg--X (I) wherein Y is allyl, or an optionally substituted phenyl or optionally substituted benzyl group, and X is a halogen, by reaction of a compound of formula (II): Y--X (II) wherein Y and X have the meanings given above, with magnesium in tertiary-butylmethyl ether solvent, characterized in that the molar ratio of magnesium to compound of formula (II) is from 1:1 to 2:1 and the reaction is carried out at 45.degree. C. or above.
式(I)化合物的制备方法:Y--Mg--X(I),其中Y是丙烯基,或者是可选择的取代苯基或可选择的取代苄基,X是卤素,通过将式(II)化合物与镁在三丁基甲基醚溶剂中反应而得到,式(II)化合物为Y--X(II),其中Y和X具有上述给定的含义,其特征在于镁与式(II)化合物的摩尔比为1:1至2:1,反应温度在45℃或以上。
