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 …

In organic chemistry, thioketones (from Ancient Greek θεῖον (theion) 'sulfur'; also known as thiones or thiocarbonyls) are organosulfur compounds related to conventional ketones in which the oxygen has been replaced by a sulfur. Instead of a structure of R2C=O, thioketones have the structure R2C=S, which … See more The C=S bond length of thiobenzophenone is 1.63 Å, which is comparable to 1.64 Å, the C=S bond length of thioformaldehyde, measured in the gas phase.
