Asymmetric Mn(III)-salen catalyzed epoxidation of simple cis-disubstituted and trisubstituted alkenes in mild conditions was performed using tetrabutylammonium monopersulfate (Bu4NHSO5) as the oxidant together with N-methylmorpholine N-oxide as an additive. Particularly high yields of epoxides (up t

Asymmetric epoxidation of unfunctionalized alkenes is reported using chiral (salen)Mn(III) complexes 1-$ together with a carboxylate salt cocatalyst in the presence of either aqueous H202 or anhydrous urea-H202 adduct as oxidant. Several simple soluble salts (acetates, formates, benzoates) were stud
Catalytic epoxidation of two unfunctionalized alkenes, 1,2\_dihydronaphthalene and tranx-e-methylstyrene, is reported using achiral and chirol (Salen)Mn(III) complexes l-3 together with a nitrogen heterocycle as axial ligand in the presence of 30 %I aqueous hydrogen peroxide as oxidant. Typically, t
