Abstract:
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.
