ABSTRACT The reaction of 1,2-ethanedithiol and 1,3-propanedithiol with π-deficient compounds afforded various oxidation–reduction and cyclized products under mild conditions. Heterocycles containing one sulfur atom (e.g. analogues of seriniquinone) were also obtained. The structures of the products were elucidated by NMR, IR, mass spectral data, and elemental analyses. The mechanisms were also discussed

Two general methods have been developed permitting the effective reduction of ketene dithioacetals to give substituted dithianes. Reduction with magnesium in methanol is less reliable than reduction with zinc in acetic acid. The greater inconsistency of magnesium in methanol has been investigated by a cyclic voltammetric study of the substrates. The utility of the dithianes has been successfully illustrated
