ABSTRACT β-Dioxodithioate were produced easily from active methenyl precursors, carbondisulfide and RX with potassium carbonate as base. By a selective basic assistant cleavage of a carbon–carbon bond at the β-dicarbonyl unit of β-dioxodithioate and the subsequent alkylation with RX/R′X in situ, single or mixed α-oxo ketenedithioacetals were obtained in good yields.
