It was found that the selectivity and the yield of coadduct were greatly affected by the pressure of carbon dioxide,the reaction temperature and the amounts of alcohol and base used.展开更多
Citronellal was the major product of catalytic oxidation of dihydromyrcene with oxygen using the catalyst comprised of (MeCN)2PdClNO2 and CuCl2 in a tertiary alcohol in supercritical carbon dioxide. It was found that ...Citronellal was the major product of catalytic oxidation of dihydromyrcene with oxygen using the catalyst comprised of (MeCN)2PdClNO2 and CuCl2 in a tertiary alcohol in supercritical carbon dioxide. It was found that the chemoselectivity of the reaction and the yield of citronellal were greatly affected by the pressure of carbon dioxide, the reaction temperature and the molar ratio of Pd/Cu.展开更多
