Article abstract of DOI:10.1246/bcsj.68.89

The catalytic activity of binary oxides of Al2O3-Eu2O3, Al2O3-Sm2O3, Al2O3-NdO3, Al2O3-Pr6O11, and Al2O3-Y2O3 were checked in the transformations of α and β-pinene oxides.Al2O3-Eu2O3 and Al2O3-Nd2O3 are found to be best catalysts for α-pinene oxide isomeriztion.Among the oxiranes, α-pinene oxide showed more activity mainly yielding 2,2,3-trimethyl cyclopentene-1-acetaldehyde. β-pinene oxide produced trans-myrtanal and myrtanol.
