“…Accordingly, the development of efficient, practical, and high selective oxidation methods of furan derivatives has attracted considerable attention. Numerous stoichiometric metal oxidants and organic oxidants have been explored to achieve these transformations, which include metal oxidants [Ce(NO 3 ) 6 (NH 4 ) 2 , MnO 2 , and Pb(OAc) 4 ] peroxides [ m -CPBA, dimethyl dioxirane, CH 3 CO 3 H, MMPP, Fe 2+ /H 2 O 2 , UHP/MTO, Mo(CO) 6 /TBHP, t BuOOH/Ti(IV), and oxone] and other oxidants (SeO 2 , HNO 3 /AcOH, NaH 2 PO 4 /NaClO 2 , DDQ, Br 2 , and Selectfluor). Molecular oxygen represents the most inexpensive, readily available, and environmentally benign oxidant; therefore, aerobic oxidation methods offer a compelling alternative .…”
