WebJan 26, 2007 · The sulfhydrolysis ofβ-alkoxy (or alkylthio) vinylene thioketones has provided a convenient synthetic approach to some β-mercaptovinylene thioketones (β-di-thiodiketones). The synthesis of the first β-cyanovinylene thioketone stabilized as a trimer is described involving the cyanolysis of β-alkoxy and β-chlorovinylene thioketone. WebAs nouns the difference between ketone and thioketone is that ketone is a homologous series of organic molecules whose functional group is an oxygen atom joined to a carbon atom—by a double bond—in a carbon-hydrogen based molecule while thioketone is any analogue of an ketone, of general formula RC(=S)R', in which the oxygen has been …
