With both TEMPO and O2 (in air) as the homogeneous redox mediators, BiBrO as the heterogeneous semiconductor photocatalyst, the first example of semi‐heterogeneous photocatalytic decarboxylative phosphorylation of N‐arylglycines with diarylphosphine oxides was established. A series of α‐amino phosphinoxides were efficiently synthesized. [ABSTRACT FROM AUTHOR]

With both ferrocene and air as the redox catalysts, for the first time, the low-cost natural ilmenite (FeTiO3) was successfully used for photocatalytic bond formations. Under the assistance of a traceless H-bond, and HCHO as the methylene reagent, a variety of imidazo[1,5-a]quinoxalinones were semi-heterogeneously photosynthesized in high yields with good functional group compatibility.

With formaldehyde as an atom-economical carbonyl synthon, the EtOH-catalyzed electrochemical multicomponent synthesis of various imidazolidine-fused sulfamidates was developed. A wide range of products were obtained in good to excellent yields under organic oxidant-free, energy-saving and mild conditions. The mechanistic study revealed that the in situ generated ethoxide played a crucial role in producing aminomethylene radicals at a lower voltage. [ABSTRACT FROM AUTHOR]

The semi-heterogeneous g-C3N4/NaI dual catalytic system-driven C–C bond formation between quinoxalin-2(1H)-ones and arylhydrazines under blue light irradiation has been reported for the first time. The photo-generated hole acted as a traceless oxidant to turn over the iodide salt redox catalyst cycle and the photo-generated electron served as a clean reductant to promote the bond formation process. A wide range of 3-arylquinoxaline-2 (1H)-ones were obtained in high yields with excellent functional group tolerance. [ABSTRACT FROM AUTHOR]

We developed a novel and efficient method for the synthesis of various 3‐alkylated quinoxalin‐2(1H)‐ones (32 examples, 70%–96% yields) through electron donor‐acceptor complex enabled alkylation of quinoxalin‐2(1H)‐ones with N‐ hydroxyphthalimide esters as the alkyl source and Na2S as the catalytic electron donor under external photocatalyst‐, oxidant‐ and additive‐free conditions.

The first paired electrolysis-enabled arylation of quinoxalin-2(1 H )-ones was achieved using cyanoarenes as the arylation reagents. A variety of 3-arylquinoxalin-2(1 H )-ones with various important functional groups were obtained in moderate to good yields under metal- and chemical oxidant-free conditions. With a pair of reductive and oxidative processes occurring among the substrates and reaction intermediates, the power consumption can be dramatically reduced.
