摘要

本文首次采用色谱-质谱联用技术研究了钯络合物存在下莰烯乙酰氧基化的均相催化反应，主要形成醋酸异硼镁酯。反应按化学计量量进行，但可以转化为催化模式。指出了一些伴生产物的形成方式，并找到了反应产物在反应区积累过程中抑制这一过程的解释。将所得结果与酸催化实验结果进行了比较，结果表明，在75 ~ 80℃的条件下，底物转化率可达99 ~ 100%，乙酸异鸟酯收率可达89%。

HOMOGENEOUS-CATALYTIC ACETOXYLATION OF CAMPHENE

The homogeneous catalytic reaction of camphene acetoxylation in the presence of palladium complexes with the predominant formation of isobornyl acetate was studied for the first time using chromatography-mass spectrometry. The reaction proceeds stoichiometrically, but can be converted to catalytic mode. Ways of formation of some accompanying products were shown and an explanation was found for the inhibition of the process during the accumulation of reaction products in the reaction zone. The obtained results were compared with the results of experiments under acid catalysis and it was shown that at a temperature of 75-80°C it is possible to achieve 99-100% conversion of the substrate with an 89% yield of isobornyl acetate.
