摘要:

三价铑在氧化条件下催化N-烷基苯甲酰胺与醌反应生成芳基醌. 在氧化还原中性条件下, 经过偶联和内酯化反应可以得到2-羟基-6H-苯并[c]吡喃-6-酮.

关键词: 三价铑, 碳氢活化, 苯甲酰胺, 芳基醌

Abstract:

Rh(III)-catalyzed C-H activation of N-(alkyl)benzamides in the oxidative coupling with various quinones. In addition, under redox-neutral conditions, 2-hydroxy-6H-benzo[c]chromen-6-ones were also obtained via a cascade of cross-coupling followed by lactonization.

Key words: Rhodium(III), C-H activation, Benzamides, Arylquinones
