Chemoselective photooxidation: Tetra‐ O ‐acetylriboflavin and blue light mediate the selective oxidation of sulfides to sulfoxides without overoxidation to sulfones. Reaction is very effective in ethanol/water (95:5, v / v ) mixture reaching a quantum yield of Φ =0.60. The photooxidation reaction scope includes aliphatic and aromatic sulfides including sterically hindered substrates.
