摘要：
Chiral C2-symmetric N-heterocyclic carbene (NHC) palladium diaquo complex 5b prepared from (S)-BINAM was found to be a fairly effective catalyst for the enantioselective asymmetric fluorination of oxindoles to give the corresponding products in moderate enantioselectivities along with good to excellent yields.
