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.

The synthesis of dialkyl-substituted cyclopropanes is an important challenge in with applications drug discovery and agrochemistry. Herein, we report on the gem-dialkyl situ-generated dialkyl diazo compounds under Bamford–Stevens conditions. A simple cobalt catalyst was identified to be optimal achieve high yields. Experimental computational studies suggest participation a metalloradical reaction mechanism that facilitates carbene transfer reactions provides access single step.

A visible-light-promoted three component reaction of diazo compounds, nitriles, and carboxylic acids is reported. The utilizes acceptor-only compounds as carbene precursors nitriles carbene-trapping reagents to form the key nitrile ylides. Under optimal conditions, a wide range imide products were obtained in good excellent yields. gram-scale synthesis synthetic application isoquinoline-1,3(2H,4H)-dione derivatives further proved value this method.
