摘要：

The catalytic enantioselective fluorination of alpha-cyanoalkylphosphonates catalyzed by chiral palladium complexes was examined. Treatment of alpha-cyanoalkylphosphonates with N-fluoro-benzenesulfonimide as the electrophilic fluorinating reagent under mild reaction conditions afforded the corresponding alpha-fluorinated alpha-cyanoalkylphosphonates in excellent yields with high enantiomeric excesses (80-91%).
