air: A convenient and general iron-catalyzed oxidation of internal olefins, electron-deficient olefins, and styrenes to ketones by using 1 atm of air as the sole oxidant has been developed. This protocol efficiently incorporates atmospheric O2 into synthetically useful compounds under mild reaction conditions, which renders it environmentally benign, economical, and operationally simple.
