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.

‐Phenyl Phenylcarbamothioates: An Odorless and Chemo‐selective Chan–Lam Reaction to Construct C−S Bond
A series of O/N-alkyl S-phenyl phenylcarbamothioates were obtained smoothly by using odorless organosulfur sources and commercially available phenylboronic acids through a Chan–Lam reaction. The methodology features simple performance, odorless organosulfur source, selective C−S bond formation, and a good functional group tolerance.
A method for the selective construction of S–N/C(sp2)-S bonds using N-substituted O-thiocarbamates and indoles as substrates is reported. This protocol features good atom utilization, mild conditions, short reaction time, and wide substrate scope, which can provide a convenient path for the functionalization of indoles. In addition, the reaction could be scaled up on gram scale, showing potential application
