Palladium(ii)-catalyzed intramolecular C–H amination to carbazole: the crucial role of cyclic diacyl peroxides

Herein, we have developed an efficient Pd II -catalyzed intramolecular oxidative C–H amination under additive-free and green conditions where strained cyclic diacyl peroxide functions as both a sacrificial oxidant and a bidentate linker.
