Two novel chiral biphenyl iminium salts derived from l-acetonamine, containing electron- withdrawing 3, 3′-substituents on the biphenyl unit, have been prepared and tested as asymmetric catalysts for epoxidation of prochiral alkenes. The results are compared with those achieved using the corresponding unsubstituted system.
