Flavylium (Our oxygen goes up to three!)

Posted on: March 13, 2008 9:59 PM, by Molecule of the Day

Flavylium is an unusual heterocycle - it has a trivalent oxygen atom. These tend to be quite reactive - trialkyloxoniums, some of the most potent alkylating agents, contain them.

As in the case of tropylium, aromaticity saves the day again. What should be a very unstable compound ends up being fine even in water.

You might know flavylium from such pigments as cyanidin and delphinidin.

Cyanidin and delphinidin are considered antioxidants in metabolism. Could flavylium be used as one?
