Direct arylation reaction of heteroarenes mediated by photoinduced electron transfer
Journal of Photochemistry and Photobiology(2023)
摘要
Electron donor–acceptor (EDA) complexes are interesting chemical species that function as molecular complexes. In this context, chemists have actively studies the use of halogen bonding as a noncovalent interaction in photochemistry. This study focused on developing a direct arylation reaction using aryl radicals generated by photoinduced electron transfer (PET) through halogen-bonding interactions. The study also involves optimizing reaction conditions for a photo induced direct arylation reaction using phenols as halogen bonding acceptor and plausible reaction mechanism. Our results demonstrated that this method provides a facile and efficient approach for synthesizing complex biaryls containing heteroarens using readily available heteroarenes.
