p-Toluenesulfinic acid sodium salt is used as an intermediate for the preparation of pharmaceuticals and dispersal dyes. It acts as a curing agent of grouting material. It is also used as a discharge medium of dyes and pigments. Further, it serves as a chemical intermediate in the production of fluorescent pigments and fabric adhesive. In addition to this, it is used as an electroplating brightening agent and curing agent.
Alkylation with reactive halides leads to alkyl sulfones. Alkylation of sulfinates can be carried out in a polyethylene glycol as solvent/catalyst: Bull. Chem. Soc. Jpn., 57, 613 (1984). Reaction with allylic alcohols also gives sulfones: J. Org. Chem., 55, 3274 (1990). For asymmetric sulfonylation of allylic chlorides, catalyzed by a chiral Pd complex, see: Tetrahedron: Asymmetry, 6, 643 (1995).
In the presence of CuI, iodoarenes undergo displacement in DMF to give moderate to good yields of diaryl sulfones: Tetrahedron Lett., 36, 6239 (1995).
For use as a precursor of p-toluenesulfonyldiazomethane, via Mannich reaction with formaldehyde and urethane, nitrosation and cleavage with alumina, see: Org. Synth. Coll., 6, 981 (1988):
Also undergoes free-radical reactions in the presence of Cu(II), activated either thermally or by sonication. For example, addition-cyclization of 5-heteroarylpent-1-enes: Synlett, 763 (1995):
