A vinyl sulfone is an organic compound with the formula O2S(CH=CH2)2. The molecule consisting of two vinyl groups bonded to a sulfone. It is the parent of several vinyl sulfones of the type O2S(CH=CH2)R. [1] Many vinyl sulfones are known.

Vinyl sulfones

Examples include phenyl vinyl sulfone, [2] methyl vinyl sulfone, [3] and ethyl vinyl sulfone. [4]

Preparation

Divinyl sulfone is prepared from the diacetate bis(2-hydroxyethyl)sulfide. Oxidation of this diester with hydrogen peroxide gives the sulfone. The sulfone is then pyrolyzed to induce elimination of two equivalents of acetic acid: [5]

(AcOCH2CH2)2SO2 → (CH2=CH)2SO2 + 2 HOAc (Ac = acetyl)

Other vinyl sulfones are prepared analogously to the vinyl sulfone, i.e. by H2O2-oxidation of the sulfide. [6]

Reactions and uses

Vinyl sulfones are dienophiles. Subsequent to the cycloaddition to a vinyl sulfone, the phenylsulfonyl group can be removed by reduction with zinc. [7]

Vinyl sulfones are Michael acceptors. [8] Vinyl sulfones add thiols, such as cysteine residues. [9] This same reactive nature is responsible for their major industrial use in vinyl sulfone dyes. [10]

Phenyl vinyl sulfone has been applied to ruthenium chemistry as part of olefin metathesis reactions. [11]

Vinyl sulfone has applications to protein purification, especially when linked with mercaptoethanol. [12]

Commercial applications

Vinyl sulfone has uses as a molluscicide pesticide. [13]

Safety

Like similar compounds, vinyl sulfone is a lacrymator and skin irritant. These properties are somewhat mitigated because of its low volatility. [8]
