Copper-mediated direct arylation of 1,3,4-oxadiazoles and 1,2,4-triazoles with aryl iodides

Direct arylations of 2H-indazoles on water

The efficient palladium-catalyzed synthesis of a range of substituted 2H-Indazoles via C-H arylation is reported. Reactions are performed on water and provide a direct and mild route toward 2,3-diaryl indazoles of widespread biological significance.
