Versatile radicals: MnO₂-catalyzed trifluoromethylation and azidation reactions of styrenes and enol acetates are described. The reactions used air/oxygen as the oxidant under mild conditions, with the Langlois reagent and trimethylsilyl azide as precursors for the trifluoromethyl and azide radicals, respectively. The radical species were intercepted by styrenes and enol acetates to afford trifluoromethylated alcohols/ketones and ketoazides, respectively.

二氧化锰催化的苯乙烯中间体的三氟甲基化和苯乙烯基烯烃的叠氮化

多种自由基：描述了MnO ₂催化的三氟甲基化和苯乙烯与烯醇乙酸酯的叠氮化反应。该反应在温和条件下使用空气/氧气作为氧化剂，而Langlois试剂和三甲基硅烷基叠氮化物分别作为三氟甲基和叠氮化物自由基的前体。自由基物质被苯乙烯和烯醇乙酸酯拦截，分别得到三氟甲基化的醇/酮和酮叠氮化物。
