A new chiral Fe(III)-salen grafted mesoporous catalyst for enantioselective asymmetric ring opening of racemic epoxides at room temperature under solvent-free conditions

We have designed a new mesoporous SBA-15 supported chiral Fe(III)-salen material (Fe@SBSAL) having high BET surface area and porosity. The material showed excellent catalytic efficiency in regio- and enantioselective (ee > 99%) asymmetric ring opening (ARO) of racemic meso- and terminal-epoxides...

Description
Summary:We have designed a new mesoporous SBA-15 supported chiral Fe(III)-salen material (Fe@SBSAL) having high BET surface area and porosity. The material showed excellent catalytic efficiency in regio- and enantioselective (ee > 99%) asymmetric ring opening (ARO) of racemic meso- and terminal-epoxides with various anilines at room temperature under solvent-free conditions within 1-3 h reaction time.
