Nickel peroxide oxidation of 2'-hydroxychalcones (1) gives flavones (3) in moderate yields, aurones (4) are also formed in cases where the 2/4 position of the starting 1 bears either a strong ?-donor or a ?-acceptor substituent.Flavanones (2) are dehydrogenated with this reagent to the corresponding flavones (3) in very good yields.
