A simple, mild and practical process for the direct conversion of nitriles to cyanamides was newly discovered and exhibited a wide substrate scope as well as great functional group-tolerability (36 examples). In this efficient strategy, the in situ generated amidoximes obtained from the reaction of nitriles with hydroxylamine subsequently underwent Tiemann rearrangement, producing the corresponding cyanamides with great isolated yields under SO2F2. Additionally, the control experiments reportedly shed light on the tentative mechanism involved in the formation and elimination of the key intermediate: a sulfonyl ester.

A one pot highly efficient and simple protocol for the construction of aromatic cyanamides from thiourea via desulphurization/C-N cross coupling using a cheap, readily available and air stable copper source as a catalyst has been described. Various iodobenzenes could give their respective C-N cross-coupled products in good to excellent yields under optimized reaction conditions. Further, the substrate scope has been explored.
