A method for the synthesis of a new type of onium derivative of 1,3-indanedione — N,N′-bis(1,3-indanedion-2-yl)imidazolium betaine — by anhydride condensation of N-(1,3-indanedion-2-yl)-N′-carboxymethylimidazolium betaine with phthalic anhydride was developed. The new substance is an acid and forms stable salts.
