Metal complexes of Co, Ni and Cu with the pincer ligand HN(CH(2)CH(2)P(i)Pr(2))(2): preparation, characterization and electrochemistry
- Univ. of California, Berkeley, CA (United States)
A series of Co, Ni and Cu complexes with the ligand HN(CH₂CH₂PiPr₂)₂ (HNP₂) has been isolated and their electrochemical behaviour investigated by cyclic voltammetry. The nickel complexes [(HNP₂)NiOTf]OTf and [(HNP₂)NiNCCH₃](BF₄)₂ display reversible reductions, as does the related amide derivative (NP₂)NiBr. The related copper(I) and cobalt(II) derivatives were also isolated and characterized. The addition of piperidine to [(HNP₂)NiNCCH₃](BF₄)₂ led to the formation of the new species [(HNP₂)Ni(N(H)C(CH₃)NC₅H₁₀)](BF₄)₂. The nucleophilic addition of piperidine to acetonitrile to produce HN=C(CH₃)NC₅H₁₀ was found to be catalyzed by [(HNP₂)NiNCCH₃](BF₄)₂.
