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.
由(S)-BINAM制备的手性C 2对称N杂环卡宾(NHC)钯二茂合物5b被发现是对羟吲哚的对映选择性不对称氟化的相当有效的催化剂,可以使相应的产物具有中等的对映选择性和良好的对映体选择性。优异的产量。
