A highly active and enantioselective ion‐pair sulfoxidation catalyst, consisting of an achiral iron(III)‐salen cation and a chiral phosphate counteranion, mediates the oxidization of various sulfides with high yields and enantioselectivities. The enantioselectivities observed, especially for electron‐poor substrates, represent the best results so far in manganese and iron‐salen systems. This work represents the first application of our concept of asymmetric counteranion‐directed catalysis (ACDC) to iron catalysis.
