Vinyl sulfone
From Wikipedia, the free encyclopedia
In organic chemistry, a vinyl sulfone is a functional group consisting of a vinyl group bonded to a sulfone group. Specific compounds containing this functional group are divinyl sulfone,[1] phenyl vinyl sulfone,[2] methyl vinyl sulfone,[3] and ethyl vinyl sulfone.[4]

The sulfone makes the vinyl group electrophilic, allowing it to be used as a pharmacophore for binding to the thiol of cysteine residues.[5] This same reactive nature is responsible for their major industrial use in vinyl sulfone dyes.[6]
