A novel Fe-catalyzed olefin hydroamination with aryldiazo sulfones for accessing alkylarylazo compounds has been successfully developed. Aryldiazo sulfones are used as radical acceptors, and N-N double bonds will be regenerated when an arene sulfonyl grou

A simple and convenient method for N-aminosulfonamide synthesis from the cross-coupling of aryldiazonium tetrafluoroborates and rongalite under metal-free, oxidant-free, and room-temperature conditions is reported. This method does not require an external amine source, with the aryldiazonium tetrafluoroborates participating as both an aryl radical and a potential amine source in the transformation. Mechanistic studies revealed that rongalite could act as a radical initiator, a sulfur dioxide surrogate and a reducing reagent simultaneously in this reaction.

An efficient and convenient method for the synthesis of aryl hydrazines is described via copper-catalyzed cross-coupling of aryl halides with aqueous hydrazine in PEG-400. This protocol is applicable to both electron-deficient and electron-rich aryl iodides and bromides, and even to sterically hindered substrates, giving aryl hydrazines in good to excellent yields.
