以源自蒎烯的2-氯莰烷和2,6-二氯莰烷为原料,采用微波辐照法合成了冰片烯和冰片二烯,结果表明,以叔丁醇钾作消除试剂,N,N’-二甲基甲酰胺作溶剂,微波功率400 W,辐照温度120℃条件下反应60 min,2-氯莰烷和2,6-二氯莰烷可完全转化为冰片烯和冰片二烯,得率分别可达92.1%和94.3%,纯度分别为95.6%和99.9%,该方法操作简单,环境友好,反应时间短且得率高.此外,探讨了2-氯莰烷和2,6-二氯莰烷消去反应的机理,表明该反应是一个双分子消除反应(E2)历程,只能进行顺式消去.

Bornylene and bornadiene were synthesized using 2-chlorocamphane and 2,6-dichlorocamphane as raw materials under microwave irradiation. The results showed that the optimum reaction conditions are as follows: using potassium tert-butoxide as elimination reagent,N,N’ - dimethyl formamide as solvent,with microwave power of 400 W at microwave temperature of 120℃ for 60 min,the yields of bornylene and bornadiene can be up to 92.1% and 94.3%,respectively. Microwave method is simple,eco-friendly,and has the advantage of short reaction time and high yields. Moreover,mechanism of 2-chlorocamphane and 2,6-dichlorocamphane elimination reaction was studied,the result demonstrated that this reaction is a bimolecular elimination reaction (E2) mechanism which only follows the cis-elimination.
