direct approach to alkyl/aryl heteroarene sulfonic esters using copper sulfate as the environmentally benign inorganic sulfonation reagent was first realized with the aid of isocyanide. A variety of heterocycles reacted to afford the corresponding sulfonic esters through C−H functionalization. In this transformation, the otherwise inert copper sulfate was unusually activated by an isocyanide and employed

An efficient KI-mediated chloro-oxidation of indoles was developed, using KCl/NaCl as the chlorine source and oxone as oxidant, which affording various functionalized 3,3-dichloro-2-oxindoles in moderate to excellent yields. This chlorine gas-free protocol provided a practical approach for the synthesis of a series of 3-chloro-2-oxindole derivatives.
