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.

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.
