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.
