Phosphovanadomolybdic acid catalyzed desulfurization–oxygenation of secondary and tertiary thioamides into amides using molecular oxygen as the terminal oxidant
In the presence of phosphovanadomolybdic acids, secondary and tertiary thioamides could be converted into amides using molecular oxygen and water.

Various thiocarbonyl compounds such as thioamides, thiocabamate, thiocarbonate, trithiocarbonate, and thioketone were readily reacted with t-butyl thionitrate (t-BuSNO2) to give the corresponding carbonyl compounds in excellent yields under mild conditions. Desulfurization seems to be initiated the selective nitrosation on the sulfur atom of thiocarbonyl group with t-BuSNO2.

various solvents by means of 1H NMR spectroscopy, as well as molecular dynamics (MD) and other computational analyses. Our experimental results indicate that the Z/E isomer preference of secondary (NH)thioamides of N-phenylthioacetamides shows substantial solventdependency, whereas the corresponding amides do not show solventdependency of the Z/E isomer ratios.

A facile and efficient approach to the synthesis of secondary thioamides from ketoximes via Beckmannrearrangement has been established, using phosphorus pentasulfide as a dehydrating and thiating agent. It is also efficient for the preparation of primary thiobenzamide from benzaldoxime. This approach features simple‐operation, easy‐control and good to excellent yields.
