A non-heme iron complex catalyzes highly enantioselective epoxidation of olefins with H2O2 in the presence of catalytic amounts of carboxylic acid additives. Ligand and carboxylic acid synergistically cooperate in promoting efficient O-O cleavage and creating highly chemo- and enantioselective epoxidizing species which provide a broad range of epoxides in synthetically valuable yields and short reaction times.
