A series of zinc indium sulfide (ZnIn2S4) were synthesized by solvothermal methods in different solvents. After characterizations, the ZnIn2S4 prepared ethanol (i.e., ZIS-1) showed highest photocurrent density. With ZIS-1 as a photocatalyst, direct C–H azolation N-heterocycles including quinoxalin-2(1H)-ones, quinazoline, and 2H-benzo[b][1,4]oxazin-2-ones (32 examples) was realized an air atmosphere under blue light (456 nm). More importantly, microspherical photocatalyst is stable catalytic process can be used at least five times while reactivity remains unchanged. In addition, this practical approach also applicable to some other complex molecules interest, such ibuprofen isoxepac.

We disclosed herein a straightforward photochemical method for the construction of phenanthridines containing synthetically useful succinate unit. The reaction occurred under visible-light irradiation with cheap eosin Y Na as photoredox catalyst and diazo compound precursor. Under optimal conditions, wide range were obtained in moderate to good yields. Note that units final heterocycles could be easily transformed into many valuable structures, such γ-butyrolactone, dihydrofuran-2(3H)-one, tetrahydrofuran. Mechanistic experiments performed support proposed mechanism.

Abstract Cyclopropanes are one of the most important strained rings existing in various pharmaceutical products and secondary metabolites. They also widely used total synthesis natural products, medicinal chemistry, materials science. In past years, photochemical cyclopropanation has been gradually developed as a robust attractive synthetic method to prepare diverse cyclopropane backbones. this review, we summarize recent advances visible light‐mediated synthesis, especially using carbene transfer strategy photocatalytic radical reactions.
