A general one-pot synthesis of 2H-indazoles using an organophosphorus-silane system
A simple and direct approach for the regioselective construction of the privileged 2H‐indazole scaffold is described. The developed one‐pot strategy involves phospholene‐mediated N−N bond formation to access 2H‐indazoles.

Palladium-Catalyzed Direct C7-Arylation of Substituted Indazoles
A novel direct C7-arylation of indazoles with iodoaryls is described using Pd(OAc)2 as catalyst, 1,10-phenanthroline as ligand, and K2CO3 as base in refluxing DMA. Direct C7-arylation of 3-substituted 1H-indazole containing an EWG on the arene ring gave
