Simple and Highly Efficient Catalytic Thiocyanation of Aromatic Compounds in Aqueous Media

Two simple, mild, and efficient procedures for the thiocyanation of N‐heterocycles, substituted anilines (electron‐rich and electron‐deficient), and N‐substituted aromatic amines at room temperature are reported (Table 3). The first uses H₂O₂ as pollution‐free oxidant and the second H₅IO₆; both with the reagent potassium thiocyanate in H₂O as solvent. These procedures provided the target thiocyanates after a short reaction time in good to excellent yields and high regioselectivity.
