A new and efficient method for the synthesis of C-3 dicarbonyl indoles via oxidative cross-coupling of styrenes with indoles under metal-free conditions has been developed. Moreover, a broad scope of C-3 dicarbonyl indoles in moderate to good yields were obtained, and a plausible mechanism is proposed based on control and isotope-labeling experiments.

Plausible Mechanism

N-Substituted 2-pyridones are installed through the RhIII-catalyzed formal [3+3] annulation of enaminones with acrylates. Control and deuterated experiments led to a plausible mechanism involving C(sp2)–H bond cross-coupling and aminolysis cyclization.

Alkyl Iodides

An efficient method for the synthesis of alkyl indium reagents via an indium(iii) or lead(ii) halide-catalyzed direct insertion of indium into alkyl iodides is developed. NMR and ESI-MS analyses indicated the formation of a mixture of an alkyl indium dihalide (RInX2) and a dialkyl indium halide (R2InX).
