Due to the distinctive structural and electronic features present in sulfones, which have resulted in these unique functional groups being widely applied in pharmaceuticals, agrochemicals, materials, and imperative synthetic intermediates. Among those sulfonyl-containing molecules, sulfonamides are of the most importance owing to their medical *** anticonvulsants, HIV protease inhibitors, and anticancer, antibacterial, anti-inflammatory, antitumor, and antiviral agents contain a sulfonamide skeleton. In conjunction with our ongoing research into developing rongalite-based cleavage and incorporate into molecules methodologies for valuable skeletons, herein we present a simple preparation of N-aminosulfonamides under metal-free and oxidant-free conditions through the coupling of two molecules aryldiazonium tetrafluoroborates and rongalite at room ***, this method did not require an external amine source, with the aryldiazonium tetrafluoroborates participating as both aryl radicals and the potential amine source in the *** our knowledge, this represents the first reported example of rongalite being used as a source of SO for incorporation into two molecules of aryldiazonium tetrafluoroborates to obtain N-aminosulfonamides under metal-free, oxidant-free, and room-temperature conditions.

Reduced Species （HSO2^-, SO2^·-） Promoted One-Pot Efficient Synthesis of Phenyl Alkyl Selenides

引用

Chinese Journal of Chemistry 2007年第4期25卷 558-561页

作者：汤日元钟平林秋莲 School of Chemistry and Material Science Wenzhou University Wenzhou Zhejiang 325027 China

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.
