thiocyanation of a variety of arenes including aromatic amines, phenols, anisols and carbonyl compounds that possessing α-hydrogen in the presence of hydrogen peroxide and KSCN in water as a green media. This procedure is chemoselective, avoids the use of precious metals and toxic solvents and has a broad substrate scope. Easy removal from the reaction mixture and recyclability with no loss of activity are
Highly regioselective thiocyanations of indoles, anilines and pyrrole are achieved via an efficient and simple protocol using NH4SCN and diethylazodicarboxylate (DEAD) as a mild oxidant.
