The improved procedure for the synthesis of S-aryl phosphorothioates from dialkyl phosphites (H-phosphonates), aryl iodides and elemental sulfur deals with the application of rongalite (sodium hydroxy-methanesulfinate) as the radical promoter. The reactions proceeded smoothly to give S-aryl phosphorothioates in good yields. 相似文献

Direct arylsulfonylation of arylethenes with aryl iodides and sodium metabisulfite to access β-keto sulfones is described. In this reaction, rongalite (sodium hydroxymethanesulfinate) and sodium metabisulfite serve as the radical promoter and the sulfur dioxide surrogate, respectively. 相似文献

Reduced species (HSO2^-, SO2^·-) promoted one-pot synthesis of phenyl alkyl selenides has been developed. This synthetic method was achieved by reactions of diphenyl diselenide with alkyl halides at room temperature. It is noteworthy that the reactions were operated under mild reaction conditions, required short time, and got good resuits. A single electron transfer reaction mechanism was proposed for the reaction. 相似文献
