Abstract

In our previous work involving the enantioselective epoxidation of unfunctionalized olefins, 7 two soluble poly-salen–Mn(III) complexes derived from two substituted bis-salicylaldehydes and (R,R)-cyclohexane-1,2-diamine have been reported. Unlike the modified catalysts mentioned above, these two poly-salen–Mn(III) complexes can be regarded as polymers of “monomer” salen–Mn(III) catalyst, which, however, showed somewhat reduce enantioselectivities ...
