Factors governing the selective alkylation have been studied. Lithium bases favor dialkylation. For monoalkylation, a potassium base, e.g. KH in THF, should be used: J. Org. Chem., 55, 2234 (1990).

Adds to aldehydes and ketones in the presence of base, e.g. n-BuLi, to give ß-hydroxy sulfones. Conversion of the OH to, e.g. to mesylate, and elimination/desulfurative reduction with sodium amalgam provides a 1-substitued or 1,1-disubstituted alkene by the Julia olefination reaction: Tetrahedron Lett., 4833 (1973); J. Chem. Soc., Perkin 1, 829 (1978). For reaction scheme, see Ethyl­ phenyl­ sulfone, A10710. The adducts with aldehydes can also be rearranged to give the dimethyl acetals of the homologous aldehydes: J. Chem. Soc., Perkin 1, 1646 (1978). Reaction with acyl halides gives ß-keto sulfones: J. Org. Chem., 53, 906 (1988).
