Ni(II)–POCOP pincer compound [NiCl{C10H5-2,10-(OPPh2)2}] an efficient and robust nickel catalyst for the Suzuki–Miyaura coupling reactions

The Ni(II)–POCOP pincer complex [NiCl{C10H5-2,10-(OPPh2)2}] (2) based on a naphthoresorcinol frame has been synthesized in a very simple and facile manner and efficiently used in the Suzuki–Miyaura cross-coupling of different para-substituted bromobenzenes producing high yields of the corresponding biphenyl derivatives.
