Applicazioni

Divinyl sulfone acts as a cross-linking reagent for agarose gels. It is a monomer, which is used in the production of polymers with diols, urea and malonic esters. Further, it serves as a shrinkage control agent in textiles. In addition to this, it is used in the preparation of large class of fiber-reactive dyestuffs.

Note

Incompatible with strong oxidizing agents, strong acids, reducing agents, alkali metals and strong bases.

Reactive dienophile and Michael acceptor. Reacts with oximes to give bicyclic products derived from dipolar cycloaddition of a transient nitrone intermediate: Tetrahedron Lett., 29, 2417 (1988):

In the presence of thiazolium salt catalysts (see 3-Benzyl-5-(2-hydroxyethyl)-4-methyl­thiazolium chloride, L08750), the Stetter reaction with aldehydes gives 1,4-diketones by loss of SO2 from the intermediate dialkyl sulfone: Chem. Ber., 114, 1226 (1981); for a related example, see Phenyl­ vinyl­ sulfone, A14794.
