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
A convenient and efficient synthesis of sulfones from sulfinates and aryl halides was developed. The reaction occurred under UV irradiation without transition metal catalyst or photocatalyst. A radical pathway via single‐electron transfer (SET) of electron donor‐acceptor (EDA) complex was proposed based on UV‐vis spectroscopy, radical inhibiting and trapping experiments.
The first example of palladium-catalyzed protocol for the denitratedcoupling of nitroarenes with sulfinates was developed, achieving aryl and heterocyclic sulfones in moderate to excellent yields. The cyclopalladated ferrocenylimine (I) exhibited highly catalytic activity for this transformation with low catalyst loading (0.75 mol %). The efficiency of this reaction was demonstrated by compatibility

ABSTRACT An efficient and microwave-assisted simple protocol for the synthesis of symmetrical/asymmetrical diaryl sulfones through the Cu(II)-catalyzed reaction of sodium salt of sulfinic acid with aryl boronic acid has been described. Various diaryl sulfones have been synthesized in very short reaction times with moderate to very good yields. Additionally, the method is also useful for the synthesis of aryl

Abstract The recent development of selective oxidation of aromaticsulfides with molecular oxygen was highlighted. The sulfoxides and sulfones could be obtained by simply switching the reaction media, i.e., bis(2-butoxyethyl)ether (BBE) or poly(ethylene glycol)dimethyl ether (pegdme). The application of the high-boiling-point polyether as an initiator and green media can eliminate the need of large
