- 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).
- 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):
