The reaction of lactonization of olefins with carboxyalkyl radicals and Mn(OAc)3 was carried out under ultrasound irradiation at low temperatures Good yields of lactones were obtained in short reaction times. In sonochemical conditions, reoxidation of Mn(II) occurred, allowing the development of a lactonization procedure with a catalytic amount of Mn(III).
