The synthesis of anilines and indolesfrom cyclohexanones using a Pd/C–ethylene system is reported. A simple combination of NH4OAc and K2CO3 under nonaerobic conditions was found to be the most suitable to perform this reaction. Hydrogen transfer between cyclohexanone and ethylene generates the desired products. The reaction tolerates a variety of substitutions on the starting cyclohexanones.
据报道,使用Pd / C-乙烯系统可从环己酮合成苯胺和吲哚。发现在无氧条件下简单的NH 4 OAc和K 2 CO 3组合最适合进行该反应。环己酮和乙烯之间的氢转移产生了所需的产物。该反应可耐受起始环己酮上的各种取代。
Cu-Catalyzed Oxidation of C2 and C3 Alkyl-Substituted Indole via Acyl Nitroso Reagents
The selective oxidation of C2-alkyl-substituted indoles to 3-oxindole and the selective C–H oxygenation or amination of C2,C3-dialkyl-substituted indoles at C2 are reported under mild conditions. The position of the alkyl substitution on the indole directs the reaction to different pathways under similar conditions.
