Abstract: This article states the preparation of bornadiene from 2,6-dibromocanmaphane. It was synthesized from Br2 and α-pinene by addition and isomerization reactions. In this study, α-pinene was used as raw material for synthesis of 2,6-dibromocamphane. The production processes have been improved. The optimal conditions were: mole ratio of Br2 to α-pinene 2.5:1, reaction temperature 0 ℃, and reaction time 24 h. The conversion rate of α-pinene reached 97.6 %, 2,6 - dibromocamphane selectivity of 48.8 %, yield 45.6 %. Self-made 2, 6-dibromocamphane was used to synthesize bornadiene. The optimal conditions were as follows: reaction temperature 100 ℃,reaction time 5 h, t-BuOK used as elimination reagent, the mole ratio of t-BuOK to 2,6-dibromocamphane was 4:1, conversion rate of α-pinene reached 99.12 %. FT-IR, GC-MS, 1H NMR and elemental analysis were used to identify the structure of 2,6-dibromocamphane and bornadiene.
