HOMOGENEOUS-CATALYTIC ACETOXYLATION OF CAMPHENE

Abstract

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.
