• Alternatively, 1,3-dithianes can be prepared by alkylation with reactive gem-dihalides under phase-transfer conditions: Liebigs Ann. Chem., 1589 (1982).
• Precursor of cyclic dithioacetal (1,3-dithiane) derivatives of carbonyl compounds. The protection step is catalyzed by Lewis acids, e.g. BF3 etherate: Tetrahedron Lett., 871 (1971), TiCl4: Tetrahedron Lett., 24, 1289 (1983), Aluminum trifluoromethanesulfonate, B20785, or Indium(III) trifluoromethanesulfonate, 40131. Diothioacetalization can be accomplished under neutral, solvent-free conditions using Lithium trifluoromethanesulfonate, 39322, as catalyst: Tetrahedron Lett., 40, 4055 (1999). For the preparation of monocyclic dithioacetals of ?-diketones at low temperature in the presence of BF3 etherate, see: Tetrahedron, 44, 2283 (1988).
