Brominated and chlorinated manganese chiral Schiff base complexes as epoxidation catalysts

Halogenated manganese (III) chiral Schiff base complexes have been prepared and used as catalysts for enantioselective epoxidation of 1,3-cyclooctadiene and 4-chlorostyrene. Low ee values have been obtained for a terminal olefin like 4-chlorostyrene (10% with 2- and 3-Mn-( S, S) and 34% with 1-Mn-(...

Description
Summary:Halogenated manganese (III) chiral Schiff base complexes have been prepared and used as catalysts for enantioselective epoxidation of 1,3-cyclooctadiene and 4-chlorostyrene. Low ee values have been obtained for a terminal olefin like 4-chlorostyrene (10% with 2- and 3-Mn-( S, S) and 34% with 1-Mn-( S, S), Jacobsen's catalyst).
