Reactions of isobutene, methylenecyclopentane, methylenecyclohexane and methylenecycloheptane with palladium acetate were studied in acetic acid at 30 to 80°. Two types of oxidation were identified: acetoxylation to allylic acetates (methylenecycloheptane) and oxidative coupling to dimers (isobutene and methylenecyclohexane). A mechanistic study indicated that the former was produced by thermal decomposition
研究了异丁烯,亚甲基环戊烷,亚甲基环己烷和亚甲基环庚烷与乙酸钯在30-80°C的乙酸中的反应。鉴定出两种类型的氧化:乙酰氧基化成乙酸烯丙酯(亚甲基环庚烷)和氧化偶合到二聚体(异丁烯和亚甲基环己烷)。机理研究表明,前者是通过热分解最初形成的π-烯丙基配合物而产生的。推测后一种方法是通过将烯烃插入乙酰氧基钯酸酯加合物中的碳钯键中,然后消除乙酸和氢化钯元素而进行的。
