A range of electron-poor and heterocyclic sulfonamides react with phenylacetyl chlorides to produce benzhydryl derivatives in a single step. The reaction proceeds via tandem amide bond formation/Dohmori-Smiles rearrangement under the simple conditions of
A facile route to 1: H- A nd 2 H-indazoles from readily accessible acyl hydrazides by exploiting a novel aryne-based molecular rearrangement

Herein we report the transformation of readily synthesised acyl hydrazides into 2-hydrazobenzophenones via a novel molecular rearrangement pathway using aryne chemistry. The developed reaction protocol is performed under relatively mild conditions and is
Ni and Cu-catalyzed one pot synthesis of unsymmetrical 1,3-di(hetero)aryl-1: H -indazoles from hydrazine, o -chloro (hetero)benzophenones, and (hetero)aryl bromides

The nickel-catalyzed cyclization of in situ generated ortho-chlorobenzophenone hydrazone derivatives, to afford 3-(hetero)aryl-1H-indazoles, is documented for the first time. The product 1H-indazoles can be transformed subsequently in a one-pot procedure into 1,3-di(hetero)aryl-1H-indazoles via copper-catalyzed N-arylation with (hetero)aryl bromides.
