Abstract: | New efficient catalysts based on electrophilic N‐fluoro quaternary ammonium salts are reported for catalytic allylation of (E)‐N,1‐diphenylmethanimine. The chiral version of the catalyst based on cinchonidine (F‐CD‐BF4) shows high catalytic activity with approximately 94% ee and TOF (>800 h?1). The F‐CD‐BF4 is prepared from cinchonidine and Selectfluor by one‐step transfer fluorination. |
