A series of polycyclic hydrocarbons containing cyclopropane moieties 1,2-annelated or spiro-condensed with cyclooctane ring were investigated under oxidative conditions. Four oxidizing systems (O3 on SiO2, dioxirane derived from trifluoroacetone, CrO3 and RuO4, generated in situ), were employed to evaluate and compare their reactivity and usefulness. RuO4 was found to be the best one, considering its
在氧化条件下研究了一系列含有环丙烷部分 1,2-与环辛烷环缩合或螺环稠合的多环烃。四种氧化系统(SiO2 上的 O3、源自三氟丙酮的二环氧乙烷、CrO3 和 RuO4,原位生成)被用来评估和比较它们的反应性和实用性。发现 RuO4 是最好的,考虑到它的氧化能力和简单的制备程序。找到了多环烃特定氧化的条件。获得了含有环丙基羰基部分的新型环辛烷衍生物。
