The preparation of the new selenium‐bridged chromones 5a‐e is described. Compound 5c reacts with m ‐CPBA under various conditions to give the corresponding selenoxide 7 and the Pummerer products 8 and 9 . The selenides 5a‐c react with excess m ‐CPBA to form the diselenides 13a‐c . Oxidation of 13c with hydrogen peroxide afforded the chromone‐3‐seleninic acid 22 .
