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

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

antitumor, and anticancer. Herein, a magnetically induced nano copper-catalyzed efficient and mild route for the synthesis of biaryl and alkyl/aryl sulfones from aryl/alkyl halides and tosylmethyl isocyanide (TosMIC) has been developed. A variety of aryl and alkyl sulfones have been obtained in very good to excellent yields. In this newly developed protocol TosMIC acts as sulfonyl source. The catalyst
A novel arylation of sulfonamides with boronic acids to afford numerous diaryl sulfones via a visible light-mediated N–S bond cleavage other than the typical transition-metal-catalyzed C(O)–N bond activation is described. This methodology, which represents the first catalyst-free protocol for the sulfonylation of boronic acids, is characterized by its simple reaction conditions, good functional group
