Generation and Regeneration of the C(sp³)-F Bond and 1,4-NADH/NADPH via Newly Designed S-gC₃N₄@Fe₂O₃/LC Photocatalysts under Solar Light

Due to the pharmaceutical, biological, physical, and chemical properties of fluorinated compounds and 1,4-NADH/NADPH, these species have attracted a lot of attention from researchers across the chemical society. Despite their crucial significance, present methods of regenerating cofactors (1,4-NADH/NADPH) as well as inserting fluorine into organic compounds suffer from ruthless drawbacks. Herein, we designed a highly efficient S-gC₃N₄@Fe₂O₃/LC photocatalyst, and its in situ generations were accomplished by calcinations of Fe₂O₃, melamine (M), thiophenol (T), and lignin carbon (LC). The Fe₂O₃part performs similar to an additional light harvester, gifting utmost photo-generated electrons, whereas the carbon part bridges a "thoroughfare" to make easy electron transfer from Fe₂O₃to S-gC₃N₄(Schemes 1 and 2). Therefore, the newly designed S-gC₃N₄@Fe₂O₃/LC photocatalyst is more efficient for the generation and regeneration of the C(sp³)-F bond and 1,4-NADH/NADPH due to its surface active sites and defects.
