CAS:17697-12-0 | Benzeneseleninic Acid Anhydride

Benzeneseleninic Acid Anhydride is an organic compound. It is soluble in organic solvents such as ethanol and ether but insoluble in water. It acts as a mild oxidizing agent. For example, it can oxidize phenols to o-quinones and can react with some compounds containing reactive hydrogen, such as hydrazine, to form azo compounds.

Uses:

Benzeneseleninic Acid Anhydride has oxidizing properties and can be used as an oxidizing agent in organic synthesis. It is commonly utilized to oxidize selenamides and selenides, leading to the synthesis of selenoxides. Benzeneseleninic anhydride can also be employed to synthesize organic selenium compounds such as selenoethers and selenones.

Method of Preparation:

Benzeneseleninic Acid Anhydride can be prepared by two main methods. One method involves reacting benzeneseleninic acid with anhydrous sulfuric acid. The reaction product is then further purified by distillation to obtain benzeneseleninic anhydride. The other approach is through the reaction of sodium bicarbonate or potassium carbonate with selenium monomers to produce selenocarbonates, which are then reacted with sodium benzeneselenite to obtain benzeneseleninic anhydride.
