【Abstract】 In this paper, the various effects influencing activity and selectivity of catalytic esterification reaction of α pinene with acetic acid to form bornyl ester, including temperature, time, co catalyst, solvent and anion effect etc., have been studied. The better synthesis conditions in ordor to obain high yicld of bornyl ester is also given. The complex catalysis mechanism is presented that an acidic complex compound HB(AcO) 4 forms in HB solution system. It is the complex compound that affords active H + and B(AcO) - 4 in the solution, which influenecs the two distinet reaction mechanisms (ionizing and non ionizing) and controls the competitions between ring enlarging and ring opening reactions, between esterification and isomerization, so that the activity and selectivity in the formation of bornyl ester from α pinene and acetic acid are greatly improved. For all these results, the satisfied mechanistic explanations have been given.更多还原
