Anhydrous potassium carbonate has been utilized as an inexpensive, safe, and efficient basic catalyst for the synthesis of flavanones starting either from 2′-hydroxychalcones or from 2′-hydroxyacetophenones. In both the cases the favored reaction condition was either refluxing in a solvent with added catalyst or microwave irradiation on the catalyst.

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.
