Here we report a
visible-light-promoted metal-free regioselective C3-H trifluoromehtylation
reaction that proceeds via radical mechanism and which supported by control
experiments. The combination of photoredox catalysis and hypervalent iodine
reagent provides a practical approach for the present trifluoromethylation
reaction and synthesis of a library of trifluoromethylated indazoles.
Here, we provide an operationally simple protocol for the highly chemoselective deoxygenation of various functionalized N-heterocyclic N-oxides under visible light-mediated photoredox conditions with Na2-eosin Y as an organophotocatalyst.
A metal-free and visible-light-induced strategy has been established for the construction of α-ketoesters via aerobic oxidation of α-diazoesters with dioxygen in air at room temperature.
The surge of photocatalytic transformation not only provides unprecedented synthetical methods, but also triggers the enthusiasm for more sustainable photocatalysts. On the other hand, oxygen is an ideal oxidant in...
A new visible-light-mediated protocol has been proposed for the synthesis of thiosulfonates via metal-free sulfonylation of thiols with aryldiazonium and sodium metabisulphite at room temperature. This mild three-component reaction, simply...
