Table 3. Visible Light-Mediated Synthesis of Quinoxaline in the Presence of TBHP^a.

^aUnless otherwise specified, all of the reactions were carried out with α-hydroxyl ketone (1.0 mmol, 226 mg) and diamine (1.0 mmol,108 mg) in the presence of 70% aqueous TBHP (3.2 equiv, 3.2 mmol = 440 μL) illuminated under a 40 W white LED lamp for 8 h at 25 °C.
