Transition metal-catalyzed functionalization of hydrocarbons is a fundamental process of paramount importance in organic synthesis. Among the numerous existing methodologies, catalyzed atom transfer to olefins plays a pivotal role since it allows access to aziridines, 1amino alcohols, 2 diols, 2, 3 and epoxides. 1, 4 In the latter case, iodosylbenzene5 (PhIdO) 1 has been extensively used as a primary oxygen atom source in combination with ...
