Abstract The new C-scorpionate Ni(II) complex [NiCl\kappa(3)-HC(pz)(3)\]Cl (pz - pyrazol-1-yl) is the first nickel homoscorpionate tris(pyrazol-1-yl) methane type complex to be applied as catalyst for the HeckeMizoroki C-C cross coupling. The microwave-assisted reaction of butyl acrylate and 4-halogeno-anisole was efficiently catalyzed by the above Ni(II) complex, in ionic liquid medium, yielding the C-C coupling product in good yields. The stability of [NiCl\kappa(3)-HC(pz)(3)\]Cl in the ionic liquid allowed its recycling and re-use for several consecutive catalytic cycles with preserved activity. (c) 2019 Elsevier B.V.
