The Ni(II) complexes [(N--O)Ni(H)(PMe(3))] (1) and [(N--O)Ni(CH(2)CH(3))(dmso)] (3) (NwedgeO = kappa(2)-{(2,6-(3,5-(F(3)C)(2)C(6)H(3))(2)C(6)H(3))-N=C(H)-(3,5-I(2)-2-O-C(6)H(2))}) were found to be well-defined model compounds to study the reactivity of polymerization active neutral Ni(II) species toward polar vinyl monomers. Methyl acrylate (MA) insertion into the Ni(II)-hydride bond of 1 was monitored at T >or= -40 degrees C by NMR spectroscopy. 2,1-Insertion yields the functionalized Ni(II) alkyl complex [(N--O)Ni(C(alpha)H(CH(3))C(beta)(O)OCH(3))(PMe(3))] (4). Low-temperature 2D ROESY data indicate a weak Ni(II)...O=C(beta) interaction in 4. This is supported by ab initio calculations at the gradient-corrected DFT (BP86/LACPV*) level of ...
