Isomerization of Cyclooctene and Cyclododecene Oxides Catalyzed by Solid Acids and Bases

Article abstract of DOI:10.1246/bcsj.67.2351

The title reactions were carried out over seven catalysts.From cyclooctene oxide a large amount of 7-octenal was formed together with 3-cycloocten-1-ol over SiO2-Al2O3 and SiO2-TiO2, 3-cycloocten-1-ol over solid H3PO4, and cyclooctanone over FeSO4.Most catalysts except for NiSO4, Al2O3, and Tio2-ZrO2 produced 1,3-cyclododecadiene, cyclododecanone, and 2-cyclododecen-1-ol uniformly from cyclododecene oxide.Allylic alcohols were preferentially given by Al2O3 and TiO2-ZrO2.
