1-锂代环己烯的合成研究

Study on the Synthesis of 1-Lithiocyclohexene

研究了以金属锂与１ － 卤代环己烯的直接锂代合成１ － 锂代环己烯的反应。通过对反应物料的配比、反应温度和１ － 卤代环己烯种类等主要影响因素的考察， 可使１ － 锂代环己烯的收率最高可达９２－８ ％ 。

Lithiocyclohexene has been prepared from the corresponding 1-halidcyclohexene and lithium chips. Some effects of several factors on the reaction were investigated such as the type of 1-halidcyclohexene, the reaction temperature, the ratio of reactants and the amount of solvent. The yield of 1-lithiocyclohexene reached 92 8%.
