The first catalyticoxygenativeallylictransposition of unactivated alkenes into enones has been developed using an oxoammoniumsalt as the catalyst. This reaction converts various tri- and trans-disubstituted alkenes into their corresponding enones with transposition of their double bonds at ambient temperature in good yields. The use of a less-hindered azaadamantane-type oxoammoniumsalt as the catalyst
使用氧代铵盐作为催化剂,已开发出未活化的烯烃向烯酮的第一个催化氧化烯丙基转移。该反应将各种三和反双取代的烯烃转化成其相应的烯酮,并在环境温度下以双键的换位以良好的收率。使用较少受阻的氮杂金刚烷型氧铵盐作为催化剂,并使用两种不同的化学计量氧化剂(即碘代苯二乙酸盐和单过氧邻苯二甲酸镁六水合物(MMPP·6 H 2 O))的组合,对于有效促进烯酮的形成至关重要。
