Four nickelcomplexes bearing 1,2,4-triazole-based N-heterocyclic carbene backbones and a cyclopentadienyl ligand were prepd. from the corresponding 1,2,4-triazolium salts and nickelocene in THF (THF) under reflux. The obtained complexes were fully characterized, including by X-ray diffraction anal. They were then used as catalysts (5 mol-%) for the borylation of aryl bromide derivs. with bis(pinacolato)diboron
