palladium-catalyzed aryl(alkyl)thiolation of various substituted unactivated arenes is accomplished for the synthesis of diverse unsymmetrical diaryl(alkyl) sulfides in good yield employing electrophilic sulfur reagent 6 derivedfrom succinimide. The developed strategy was coupled with intramolecular arylation of a C–H bond to afford dibenzothiphene derivatives, an important moiety in material science as organic
Controllable synthesis of 3-thiolated pyrroles or pyrrolines was achieved by tuning the reaction solvents, allowing the efficient construction of bisthiolated BODIPY.

A 1,3‐aminothiolation was realized by reacting 2‐substituted cyclopropane 1,1‐dicarboxylates with sulfonamides and N‐(arylthio)succinimides. Under Sn(OTf)2 catalysis the transformation proceeded smoothly to the corresponding ring‐opened products bearing the sulfonamide in the 1‐position next to the donor and the arylthio residue in the 3‐position next to the acceptor. The procedure was extended to

An efficient acid-mediated oxythiolation of o-vinylanilides has been accomplished, employing N-(arylthio)succinimide as an electrophilic arylthiolating reagent for the synthesis of various arylthio tethered benzoxazine derivatives in good to excellent yield. The important features of this method include wide functional group tolerance, quick reaction time, absence of metal or additive, and excellent
