A series of (N2P2)Ni<sup>II</sup> complexes (N2P2 = P,P’-ditertbutyl-2,11-diphosphonito[3.3](2,6)pyridinophane) stabilized by a modified tetradentate pyridinophane ligand containing two phosphonite groups were synthesized and characterized. Cyclic voltammetry (CV) studies revealed the accessibility of the Ni<sup>I</sup> oxidation state at moderate redox potentials for these Ni<sup>II</sup> complexes. <i>In situ</i> EPR, low-temperature UV-vis, and electrochemical studies were employed to detect the formation of Ni<sup>I</sup> species during the reduction of Ni<sup>II</sup> precursors. Furthermore, the [(N2P2)Ni<sup>I</sup>(CNtBu)](SbF<sub>6</sub>) complex was isolated upon reduction of the Ni<sup>II</sup> precursor with 1 equiv of CoCp<sub>2</sub>, and was characterized by EPR and X-ray photoelectron spectroscopy (XPS). Finally, the (N2P2)Ni<sup>II</sup>Br<sub>2</sub> complex acts as an efficient catalyst for the Kumada cross-coupling of an aryl halide with an aryl or alkyl Grignard, suggesting that the N2P2 ligand can support the various Ni species involved in the catalytic C-C bond formation reactivity.

We report here a reliable green method for the synthesis of palladium nanoparticles supported on copper oxide as a highly active and efficient catalyst for Suzuki cross-coupling reaction. The experimental synthetic approach is based on microwave-assisted chemical reduction of an aqueous mixture of palladium and copper salt simultaneously using hydrazine hydrate as reducing agent. The catalyst was fully characterized using various techniques showing well-dispersed palladium nanoparticles. The catalytic activity and recyclability of the prepared catalyst were experimentally explored in the ligand-free Suzuki cross-coupling reaction with a diverse series of functionalized substrates. The synthesized Pd/CuO catalyst shows many advantages beside its high catalytic efficiency such as the recyclability of up to five times with negligible loss of catalytic activity, short reaction times, use of environmentally benign solvent systems, and mild reaction conditions.
