A photocatalytic hydroamidomethylation of azobenzenes with N,N-dimethylamides has been developed. Using tetrabutylammonium decatungstate (TBADT) as a photocatalyst, an array and reacted smoothly under visible light irradiation, affording previously unreported N-amidomethyl-N,N′-diarylhydrazines in generally high yields. Mechanistic studies indicate that the reaction is enabled by TBADT-mediated hydrogen atom transfer (HAT) photocatalysis. This work fundamentally different from reported N,N-dimethylformamide azobenzenes.

The integration of trifluoroacetyl (CF3CO) groups into organic skeletons is a key research topic in synthetic chemistry given their significant potential to boost biological activity. Despite recent developments strategies for incorporating moiety via radical intermediates, the practical utilization inexpensive and readily available trifluoroacetic acids as sources has not yet been developed. Herein, an electrochemical strategy employed achieve deoxygenative transformation directly with assistance PPh3. obtained radicals are then coupled sulfoximine species, thus enabling synthesis N-trifluoroacetylated sulfoximines. Additionally, other fluorinated alkyl carboxylic acids, including perfluoro-, difluoro-, trifluoromethylcarboxylic can also be efficiently utilized under these conditions, leading corresponding acylated Moreover, trifluoroacetylation drug-based molecules easy execution scale-up experiments highlight applicability this protocol.

The facile synthesis of N-alkyl-N,N'-diarylhydrazines has been a long-standing challenge. Here, we report photoredox-catalyzed hydroalkylation azobenzenes with alkylboronic acids, which successfully affords diverse N-alkyl-N,N'-diarylhydrazines. With an acridinium salt as the photocatalyst and upon visible light irradiation, broad range acids reacted smoothly in presence Lewis base at ambient temperature. Mechanistic studies revealed that reaction proceeds via generation alkyl radicals is facilitated by photoredox catalysis.
