A convenient and straightforward transformation of cyclic ketones with anilines at room temperature has been developed using oxoammonium salt TEMPO⁺PF₆⁻ as an oxidant. This method enabled the synthesis of a broad range of α-enaminones. The ¹⁸O-labeling experiment demonstrated that oxoammonium salt served as the oxygen transfer reagent.
