The retro-Diels-Alder reaction under flashvacuumthermolysis (FVT) conditions was applied to the synthesis of simple unstabilized thioketenes. Alternatively, these reactive thiocarbonyl compounds were obtained by FVT elimination of methyltrimethylsilyl sulfide from silylated ketene dithioacetals (and for thioketene itself from methyl trimethylsilyl dithioacetate). A synthesis of propadienethione associating
