Metal-Free Visible-Light Synthesis of Arylsulfonyl Fluorides: Scope and Mechanism

The first metal-free procedure for the synthesis of arylsulfonyl fluorides is reported. Under organo-photoredox conditions, aryl diazonium salts react with a readily available SO2 source (DABSO) to afford the desired product through simple nucleophilic fluorination. The reaction tolerates the presence of both electron-rich and -poor aryls and demonstrated a broad functional group tolerance. To shed the light on the reaction mechanism, several experimental techniques were combined, including fluorescence, NMR, and EPR spectroscopy as well as DFT calculations.

Copper-mediated tandem ring-opening/cyclization reactions of cyclopropanols with aryldiazonium salts: Synthesis of: N -arylpyrazoles

A general method for the synthesis of structurally diverse N-arylpyrazoles from readily available cyclopropanols and aryldiazonium salts is disclosed. The reaction was conducted at room temperature within minutes with a broad substrate scope and excellent regioselectivity.

Method for producing 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide

The invention provides a method for producing 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide. 2-nitroaniline is used as an initial raw material, is subjected to diazotization reaction, trifluoromethyl sulfonation reaction, fluoronation, chlorosulfonation reaction, and is reacted with ammonium hydroxide to finally produce the 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide. Comparedwith reported synthesis methods, the method for producing the 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide has the advantages that the reaction yield of the synthesis route is high, used reaction agents are economic and easy to obtain, reaction conditions are mild and controllable, and in a reaction process, column chromatography and purification are not needed, so that the method for producing the 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide has wide commercial application prospects.
