Abstract: Readily available air-stable (NHC)NiCp2 complexes (NHC is N-heterocyclic carbene, Cp is cyclopentadienyl anion ligand) can be used as efficient thermally activated precatalysts for hydroheteroarylation of olefins with various heteroarenes. According to preliminary mechanistic studies, precatalyst activation may involve reductive elimination of two Cp ligands to give 1,1’’-bi(cyclopenta-2,4-diene) and (NHC)Ni0 active species under elevated temperature.

Keywords: nickel complexes, N-heterocyclic carbenes, cyclopentadienyl anion ligand, C-H activation.
