Light-controlled cooperative catalysis of asymmetric sulfoxidation based on azobenzene-bridged chiral salen TiIV catalysts

Author affiliations

Abstract

Incorporation of azobenzene into the linker of bimetallic chiral salen TiIV catalysts allowed the photoswitchable arrangement of the two Ti(salen) units through cis/trans photoisomerization of azobenzene. The differently arranged Ti(salen) units changed their cooperative function to reflect the positional relationships, as a result, their efficiency as cooperative catalysts in asymmetric sulfoxidation could be readily controlled by light stimuli.
