Abstract

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