An effective method is described to construct C–S/S–S bond starting from O‐alkyl phenylcarbamothioates, giving diverse O‐alkyl S‐phenyl phenylcarbonimidothioates or isothiourea disulfides, by using Cu2O as catalyst in water (without phase‐transfer catalyst) or NiBr2 catalyst at room temperature, respectively, in transformations featuring easy control, environmental friendliness, and good to excellent
A series of sulfenamides was obtained smoothly from aryl thioureas and amines (mainly secondaryamines) through cross dehydrogenativecoupling reaction (CDC) in the presence of phenyliodine(III) diacetate. The protocol features easily available starting materials, easy and odorless performance, mild reaction conditions, good yields, and a broad substrate scope, illustrating its synthetic value for

In the presence of PhICl2, a series of thioester compounds containing indole structures were obtained startingfrom indoles and the masked thiols (N-arylthiocarbamates). This method has the advantage of easily available startingmaterial, metal and base-free, simple operation, mild reaction conditions, and produces good yields.
