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.
上述反应在七种催化剂上进行。在 SiO2-Al2O3 和 SiO2-TiO2 催化剂上从环辛烯氧化物中生成了大量 7-辛烯醛和 3-环辛烯-1-醇,在固体 H3PO4 催化剂上生成了 3-环辛烯-1-醇,在 FeSO4 催化剂上生成了环辛酮。除 NiSO4、Al2O3 和 TiO2-ZrO2 外,大多数催化剂都能从环十二烯氧化物中均匀地生成 1,3-环十二烯二酮、环十二酮和 2-环十二烯-1-醇。Al2O3 和 TiO2-ZrO2 优先生成烯丙基醇。
