Hexafluoro‐2‐propanol (HFIP) exhibits a unique ability to release and activate H 2 O 2 from the urea‐hydrogen peroxide adduct (UHP). This UHP/HFIP system was investigated in epoxidation of olefins, using various fluoroketones as catalysts. With reactive olefins, no catalyst was required. With monosubstituted olefins, epoxides were obtained in high yields by using catalytic amounts (3−5%) of perfluorodecan‐2‐one. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
