Fluorinated and enzymatic chemicals are widely used in society due to their chemical, physical, and biological qualities. Nevertheless, despite their vital importance, present approaches to adding fluorine to molecules and regenerating enzyme cofactors have serious flaws. For instance, numerous approaches are photocatalytic and employ stoichiometric counterparts of heavy metals. Prevailing photocatalytic approaches, on the other hand, show very poor activity, and selectivity has not been attained by heterogeneous photocatalysis, despite the several benefits such a method would provide. Here, we show how heterogeneous photocatalysis may be used to selectively create C(sp3)‐F bonds and 1,4‐NADH regeneration cofactor. Employing NiS‐NiO/S‐g‐C3N4 nanocomposite photocatalyst as a photocatalyst, NAD+ and Selectfluor as an acceptor and mild fluorine donor, effective 1,4‐NADH regeneration, and decarboxylative fluorination of carboxylic acids can be attained in very short reaction times. Furthermore, NiS‐NiO/S‐g‐C3N4 nanocomposite photocatalyst exhibits outstanding levels of robustness and photo‐catching capacity. These aspects, attached to the mild environment of the reaction scheme, exhibit a breakthrough toward the sustainable cofactor of 1,4‐NADH regeneration and synthesis of fluorinated compounds.

“…After being chemically protonated in aqueous environments, the resulting electrically reduced ROC, [Cp*Rh(bpy)], undergoes a catalytic interaction with NAD + /NADP + that results in the regeneration of NADH/NADPH (79.58/76.36%). 68 To investigate E-B and SDE-B photocatalyst for solar light-driven photo-regeneration of NADH/NADPH, photocatalytic experiments were conducted. The starting material E-B's capacity for photocatalytic NADH/NADPH regeneration was also investigated for the comparison sake.…”

Sulfur‐doped Eosin‐B (SDE‐B) photocatalysts were synthesized for the first time utilizing sublimed sulfur (S8) as a dopant in an in situ thermal copolymerization technique. Sulfur doping not only increased Eosin‐B (E‐B) absorption range for solar radiation but also improved fixation and oxygenation capabilities. The doped sulfur bridges the S‐S bond by substituting for the edge bromine of the E‐B bond. The improved photocatalytic activity of SDE‐B in the fixation and oxygenation of NAD+/NADP+ and sulfides using solar light is attributed to the photo‐induced hole of SDE‐B's high fixation and oxygenation capacity, as well as an efficient suppression of electron and hole recombination. The powerful light‐harvesting bridge system created using SDE‐B as a photocatalyst works extremely well, resulting in high NADH/NADPH regeneration (79.58/76.36%) and good sulfoxide yields (98.9%) under solar light. This study focuses on the creation and implementation of a sulfur‐doped photocatalyst for direct fine chemical regeneration and organic transformation.
