C6H5SeOOH

C6H5SeOOH, also known as benzeneseleninic acid, is an organoselenium compound. It has the chemical formula C6H5SeOOH, which indicates a benzene ring (C6H5) attached to a seleninyl group (SeOOH). In this structure, selenium is in the +3 oxidation state. Benzeneseleninic acid is a white crystalline solid and is soluble in polar organic solvents.

This compound is primarily used as an oxidizing agent in organic synthesis. Its reactivity stems from the selenium atom, which can readily accept electrons. Benzeneseleninic acid is particularly effective in the oxidation of thiols to disulfides and the oxidation of alcohols to aldehydes or ketones under mild conditions. It can also be employed in the synthesis of various organoselenium compounds. The benzeneseleninic acid moiety can also participate in other transformations, such as acting as a catalyst in certain reactions. Due to its oxidizing properties, it is typically handled with appropriate safety precautions.
