The C═C double bond cleavage on tertiary enaminones, enabling the formation of a new C–CF3 bond, has been realized as a practical method for the synthesis of α-trifluoromethyl ketones with only the promotion of TBHP and ambient heating. Control experiments support that the reactions proceed via a featured freeradical process. The deuterium labeling experiment employing D2O indicates that water participated
