甲苯溶液中惰性卤代芳烃格氏试剂的制备

The Preparation of Grignard Reagent of Inert Aromatic Halogen Hydrocarbon in Toluene

惰性卤代芳烃在格氏试剂反应中,由于反应引发困难,特别在甲苯溶液中制备尤为困难,影响了这类格氏试剂的应用。以镁粉为原料,以无水甲苯为溶剂,在一定条件下,制备了卤代芳烃的格氏试剂,拓展了其工业化应用,并对影响该格氏试剂反应的各种因素进行了探讨。

The Inert aromatic halogen hydrocarbon take the place of Grignard reagent reaction , because response initiate difficult in preparation, especially in the toluene solution, has influenced the industrialized application of this each .This text take ordinary magnesium powder as start material, begain the reaction in anhydrous toluene. It gaves a good result of preparing the Grignard reagent of inert aromatic halogen hydrocarbon under the applied condition, and expand further its industrialized application. The various functionary factors have also been taken into consideration in Grignard reagent reacted .
