Sulfonyl azides have been widely used as sulfonamido, diazo, and azido donors, as well as all-nitrogen 1,3-dipoles donors in synthetic chemistry. Here, the sulfonyl azides were used as efficient sulfonyl donors, which is very unusual. Trifluoromethanesulfonic acid-induced formation of the sulfonyl cation reactive species from sulfonyl azides was developed and used for the first time to couple various

catalyzed sulfonylation reaction of aryl, heteroaryl, and vinylhalides has been achieved for the first time. This newly developed sulfonylation protocol provides a versatile method for the synthesis of diverse aromatic sulfones at room temperature and shows excellent functional group tolerance. The electrophilic coupling partners are not limited to aryl, heteroaryl, and vinyl bromides and iodides, but also

Aromatic electrophilic substitution reactions such as alkylation, acylation, benzoylation, and sulfonylation were studied in the presence of a catalytic amount of Cu(OTf)2 and Sn(OTf)2. Cu(OTf)2 was very efficient for alkylation, acylation, and benzoylation reactions. However, in case of sulfonylation reactions, Sn(OTf)2 gave better results.

An efficient and convenient method for the synthesis of diaryl sulfones was developed through the Cu‐catalyzedcross‐couplings of arylsulfonyl chlorides and arylboronicacids at room temperature in open air. This method is characterized by the use of inexpensive and readily available catalyst and substrates, mildreaction conditions, wide functionality tolerance, short reaction times for most substrates
