✦ Synopsis

Chiral (salen)manganese complexes, which are selectively perfluoroalkylated salen complexes were found to be efficient and chemoselective catalysts in the presence of soluble in perfluorocarbons, were synthesized and tested as epoxidation catalysts in fluorous-organic two-phase systems.

several oxygen donors, but enantioselectivities were generally poor. An interesting exception to this behaviour The immiscibility of the perfluorocarbons with regular organic solvents allowed a quick and effective separation of was observed in the asymmetric epoxidation of indene that provides indene oxide with 70-92% enantiomeric excess. the catalyst from the products. These unprecedented related to the use of perfluorocarbons and by the cost of 1990 of (salen)manganese(III) complexes as chiral cata-
