Sulfones are prepared by alkylation of sulfinate salts under solid-liquid phase-transfer catalysis without solvent; dithioacetals are obtained by heterogeneous uncatalyzed reactions of potassium arenethiolates and gem-dihaloalkanes. In both cases, the yields are high and the reaction conditions are mild. Some limitations are given.
