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
