Improved selectivity and decreased formation of overoxygenated byproducts were achieved by using a MeCN/H 2 O biphasic system for the iron‐catalyzed oxidation of benzene to phenol with H 2 O 2 . Under optimized reaction conditions with 5‐carboxy‐2‐methylpyrazine‐ N ‐oxide as the ligand for iron [Eq. (1)] a benzene conversion of 8.6 % and selectivities based on benzene and H 2 O 2 of 97 and 88 %, respectively, were obtained.
