Stable Methylnickel Compounds, II. Methyl(trimethylphosphine)nickel Hydroxide and Related CompoundsMethods of preparation and properties of methylnickel dimers [LNi(CH3)X]2 (L = (CH3)3P, X = OH, OCH3, OC2H5, OSi(CH3)3, OC6H5, OC6H4CH3-(p), O2CH, O2CCH3, Cl) are presented. The positions of equilibria of cis and trans isomers are determined from their low temperature 1H n.m.r. spectra. Mixed bridged complexes [LNi(CH3)X]. [LNi(CH3)Y] (L = (CH3)3P, X = OCH3, Y = OH, OC2H5, OC6H5) only occur in the cis configuration. Addition of trimethylphosphine ligands affords monomers L2Ni(CH3)X (L = (CH3)3P, X = OC6H5, OC6H4CH3-(p), O2CCH3, Cl).
Notes:
Es werden Darstellung und Eigenschaften zweikerniger Methylnickelverbindungen [LNi(CH3)X]2 (L = (CH3)3P, X = OH, OCH3, OC2H5, OSi(CH3)3, OC6H5, OC6H4CH3-(p), O2CH, O2CCH3, Cl) beschrieben. Aus den 1H-NMR-Spektren bei tiefen Temperaturen kann die Lage der Gleichgewichte zwischen cis- und trans-Formen bestimmt werden. Gemischt verbrückte Komplexe [LNi(CH3)X]. [LNi(CH3)Y] (L = (CH3)3P, X = OCH3, Y = OH, OC2H5, OC6H5) werden nur in der cis-Konfiguration beobachtet. Mit Trimethylphosphin werden aus den zweikernigen Titelverbindungen die monomeren Komplexe L2Ni(CH3)X (L = (CH3)3P, X = OC6H5, OC6H4CH3-(p), O2CCH3, Cl) gebildet.
