Study on the Synthesis of Bornadiene

α-Pinene was used as raw material for synthesis of 2,6-dichlorocamphane. Then 2,6-dichlorocamphane was used to synthesize bornadiene. The optimal conditions of 2,6-dichlorocamphane synthesis were:mole ratio of NaHCO3 to α-pinene 1:1, reaction temperature -10℃, and reaction time 7 h. The optimal conditions of synthesizing bornadiene by 2,6-dichlorocamphane were:reaction temperature 120℃, reaction time 3h, t-BuOK as eliminating reagent, mole ratio of t-BuOK to 2,6-dichlorocamphane 4:1, DMF as solvent. FT-IR, GC-MS, 1HNMR and elemental analysis were used to identify the structures of 2,6-dichlorocamphane and bornadiene.
