valuable precursors for aryl radicals upon treatment with manganese triacetate. Under these oxidative conditions the intermediately generated aryl radicals undergo addition to olefins to give the arylhydroxylation products A in the presence of dioxygen. In the absence of dioxygen, for some olefins double olefin addition and subsequent homolytic aromatic substitution provide tetrahydronaphthaline derivatives
经三乙酸锰处理后,芳基硼酸被证明是芳基自由基的有价值的前体。在这些氧化条件下,在双氧存在下,中间产生的芳基与烯烃加成,得到芳基羟基化产物A。在不存在双氧的情况下,对于某些烯烃,双烯烃加成和随后的均相芳族取代提供了中等至良好收率的四氢萘衍生物B。
