The ruthenium-catalyzed oxidation of alkanes with tert-butyl hydroperoxide and peracetic acid gives the corresponding ketones and alcohols highly efficiently at room temperature. The former catalytic system, RuCl(2)(PPh(3))(3)-t-BuOOH, is preferable to the oxidation of alkylated arenes to give aryl ketones. The latter system, Ru/C-CH(3)CO(3)H, is suitable especially for the synthesis of ketones and
在室温下,钌用氢过氧化叔丁基和过氧乙酸催化的烷烃氧化反应可高效地产生相应的酮和醇。前者的催化体系RuCl(2)(PPh(3))(3)-t-BuOOH比氧化烷基化的芳烃更可产生芳基酮。后一种体系Ru / C-CH(3)CO(3)H特别适用于从烷烃合成酮和醇。在室温下,钌在三氟乙酸/ CH(2)Cl(2)中用CH(3)CO(3)H催化钌催化的环己烷氧化,得到三氟乙酸环己酯和环己酮,其转化率为90%,选择性为90%(85:15) 。机理研究表明,碳氢化合物的这些催化氧化涉及氧代钌物种作为关键中间体。
