Synthesis and Characterization of (-)-Dibornyl Oxalate
2015
Dibornyl oxalate was synthesized by the reaction of natural (-)-borneol with oxalyl chloride under the optimized reaction conditions: temperature 35 ˚C , time 1 h and the molar ratio of (-)-borneol and oxalyl chloride 1.0 : 0.6. The reaction underwent in good selectivity as 99 % for target product which can be easily purified to 99.9 % through recrystallization. The structure of (-)-dibornyl oxalate was characterized by GC-MS, FT-IR, 1 H NMR and 13 C NMR.
