Abstract
AbstractUsing Ce(SO4)2 or Mn(OAc)3 as oxidant, dibenzo crown ethers such as dibenzo‐18‐crown‐6 (1) and dibenzo‐24‐crown‐8 (5) and benzo‐12‐crown‐4 (7) reacted smoothly with sodium perfluoroalkanesulfinates (2a‐2e) to give the corresponding perfluoroalkylated products (3,4,6,7) in good yields with two isomers obtained in the case of dibenzo crown ethers. This provides a facile synthesis of perfluoroalkyl‐containing crown ethers.
