Phenyl vinyl sulfone, 99+%


Chemical Properties

Formula Weight
Melting point
It is soluble in most common organic solvents.


Phenyl vinyl sulfone is used as building blocks in the synthesis of a number of organic substances, participate in polymerization reactions, nucleophilic addition reaction, and in cycloaddition reactions. It is also used in the used in the synthesis of reactive dyes, synthesis of textile fibers, in particular cellulose fibers such as cotton and linen. Other applications in the field of medicine includes as powerful inhibitors of certain enzymatic processes. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dye stuff.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Stable under recommended storage conditions. Keep away from strong oxidizing agents.

Reactive dienophile. Can function as an acetylene equivalent if benzenesulfinic acid is eliminated thermally from the Diels-Alder adduct to form an olefinic double bond: J. Am. Chem. Soc., 100, 1597 (1978).

Can also behave as an activated form of ethylene if the sulfone group is cleaved from the adduct, e.g. with Na amalgam, with the possibility of prior alkylation of the adduct: J. Org. Chem., 48, 4976 (1983):
