High-boiling dipolar aprotic solvent. Compare Dimethyl­ sulfoxide, A13280, N,N-Dimethyl­acetamide, A10924 and 1-Methyl-2-pyrrolidinone, A12260.

Solvent for nitrations using Nitronium tetrafluoroborate, B20167.

Widely used as solvent in the nucleophilic displacement of chloroaromatics with F- (Halex fluorination). For example, chlorinated benzaldehydes were converted to their fluoro-analogues by heating with KF in tetramethylene sulfone at 220o: J. Fluorine Chem., 46, 529 (1990). Nitro groups have also been displaced by F- by heating in the presence of tetramethylammonium chloride and phthaloyl chloride as a nitrite trap: J. Org. Chem., 56, 6406 (1991). See, however, Tetrahydrothiophene 1-oxide, A17502 and Potassium fluoride, 14130.

Use of this solvent makes possible the reduction of alkyl bromides to alkanes by NaBH4: Tetrahedron Lett., 3495 (1969).

Can be doubly metallated at the ɑ-positions with strong bases such as NaNH2, LiNH2 or n-BuLi, and the resulting dianion reacted with one or two equivalents of benzophenone to give the mono- or bis-adduct respectively: J. Org. Chem., 35, 1834 (1970); J. Organomet. Chem., 59, 53 (1973). For alkylation of the monolithio-derivative, see: Synth. Commun., 18, 583 (1988).
