A method for the construction of sulfinamides via the copper‐catalyzedelectrophilic amination of sulfenate anions usingN‐benzoyloxyamines as the amination reagents. This procedure featured with the capture of in‐situ generated sulfenate anions from β‐sulfinyl esters under mild conditions, which provides an efficient strategy for the synthesis of diverse sulfinamides in moderate to good yields.

We report the synthesis of sulfinamides using organometallic reagents, a sulfur dioxide reagent, and nitrogen based-nucleophiles. The addition of an organometallic reagent to the commercially available sulfur dioxide surrogate, DABSO, generates a metal sulfinate which is reacted with thionyl chloride to form a sulfinyl chloride intermediate. Trapping the sulfinyl chlorides in situ with a variety of
An aminoquinolate diarylboron (AQDAB) and tetrabutylammonium iodide (TBAI) co-catalyzed photoredox process for N-functionalization of NH-sulfoximines/sulfonimidamides has been successfully developed. This protocol can afford the corresponding N-sulfenylated and N-phosphonylated products in good to excellent yields under conditions without metallic (photo)catalysts, external oxidants, or acidic/basic
