Nitrogen-containing organic compounds are extensively found in bioactive natural products and pharmaceutical materials, and those materials have been highlighted the importance in the pharmaceutical market and electronics industry. Carbazole and its derivatives are also receiving importance due to their versatile medicinal uses and optoelectronic abilities. While much effort to construct the intramolecular C-N bond formation has been continued, C-N bond formation under mild condition is still a challenging task for organic synthetic chemists. Herein, we conducted the intramolecular C-H bond amination of N-benzenesulfonyl amidobiphenyl (BSAB), using only light and plasmonic Au nanoparticles as photocatalysts in the absence of hazardous solvent. We found that the cleavage of N-S bond of BSAB and the formation of C-N bond has occurred simultaneously. Consequently, we realized that the 9H-Carbazole was synthesized in the presence of plasmonic Au nanoparticles and visible light. |
