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 visible-light-assisted, copper-catalyzed sulfonylation of arylhalides with sulfinates is reported. In our protocol, a single ligand CuI photocatalyst formed in situ was used in the photocatalytic transformation. Diverse organosulfones were obtained in moderate to good yields. This strategy demonstrates a promising approach toward the synthesis of diverse and useful organosulfones.

The CuCl-catalyzed coupling of aryl chlorides and sulfinic acid salts provides a simple and extremely efficient route to unsymmetrical aryl sulfones in high to excellent yields under microwave irradiation within 3-30 minutes.
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

inexpensive, non‐toxic and environmentally benign catalytic system comprised of magnetically separable copper ferrite (CuFe2O4) nanoparticles has been developed for the synthesis of diaryl, alkyl/aryl sulfones. Arylsulfinic acid salts are coupled with various alkyl/aryl halides/boronicacids to afford the corresponding diaryl, alkyl/aryl sulfones in good to excellent yields under the identical catalytic system
由可磁分离的铁氧体铜(CuFe 2 O 4)纳米粒子组成的可回收,廉价,无毒且对环境无害的催化体系已经开发出来,用于合成二芳基,烷基/芳基砜。在相同的催化体系下,将芳基亚磺酸盐与各种烷基/芳基卤化物/硼酸偶联,以良好或优异的收率得到相应的二芳基,烷基/芳基砜。宽泛的官能团耐受性,加上通过施加外部磁场即可轻松回收催化剂,以及连续五个连续循环始终如一的高催化效率,使得该方案在操作上具有吸引力。
