A novel and convenient method for the synthesis of aryl thioamides from aryl aldehydes and tetramethylthiuram disulfide (TMTD) without the use of sulfurating reagent was explored. In the presence of CuI and di- tert -butyl peroxide (DTBP), various aryl thioamides were prepared with good to excellent yields, tetramethylthiuram disulfide as thioamide source is essential for this transformation. The protocol features broad substrate scope, nice yields, operability and commercially available and inexpensive raw materials, showing its practical synthetic value in organic synthesis.

A metal-free C[dbnd]C bond cleavage reaction of β-nitrostyrenes in the presence of elemental sulfur and secondary amines/amides is described. Elemental sulfur serves as both a raw material and an oxidant for C[dbnd]C bond cleavage, and secondary amines or amides are both feasible nitrogen sources. Besides mild reaction condition and simple work-up procedure, the method provided thioamides with good to excellent yields.

Thiourea as a sulfur atom transfer reagent was applied for the synthesis of aryl thioamides through a three-component coupling reaction with aryl aldehydes and N,N-dimethylformamide (DMF) or N,N-dimethylacetamide (DMAC). The reaction could tolerate various functional groups and gave moderate to good yields of desired products under the transition-metal-free condition.
