A system of coordinatively unsaturated metal complexes is introduced as a mobile-phase additive for reversed-phase high performance liquid chromatog. (RP-HPLC). Unlike previous ionic metal dopants, bis(2,2,6,6-tetramethylheptane-3,5-dionato)nickel(II) is a neutral, square planar complex capable of producing highly selective and efficient separations of polar compounds on hydrocarbonaceous phases. Interaction with the metal complex, and the subsequent increase in a solute’s retention, is shown to be dependent on steric, dipole, and solvation effects. The complex is transparent in the UV region of the spectrum, does not fluoresce, and produces no band broadening; equilibrium is achieved in <30 column volumes Chromatograms, which illustrate the selective separation of aromatic amines and pyridine derivatives obtained, are provided.

The neg. chem. ionization mass spectra of ML2 (HL = 2,2,6,6-tetramethylheptane-3,5-dione; M = Co, Ni, Cu, Zn], obtained using the halogenated reagent gases, NF3, CF2Cl2 and CF3Br, are presented. Thermalized electrons are captured by ML2 (M = Co, Ni, Cu) to produce mol. ions in which the oxidation state of the metal has been reduced. Lewis acid-base addition of halide ions to the metal to produce adduct ions occurs with all complexes. Reactions between radicals and ML2 also occur to produce adduct mols. which may be ionized by thermalized electrons or halide ions in the same manner as the parent complexes. Halogen radicals react by ligand displacement and homolytic substitution of the ligand while halogenated Me radicals undergo oxidative-addition to the metal. Clustering reactions also occur to produce ions containing 2 metal atoms.

HPLC of Formula: 14481-08-4. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II), is researched, Molecular C22H38NiO4, CAS is 14481-08-4, about High-pressure mass spectra and gaseous ion chemistry of metal β-diketonates with bulky substituents. Author is Schildcrout, Steven M..

Mass spectra at normal and elevated pressures are reported and interpreted for chelates of the 2,2,6,6-tetramethyl-3,5-heptanedione anion with Cr(III), Fe(III), Co(II), Co(III), Ni(II), Cu(II), Zn(II), and Al (III). At the higher pressures in each case primary pos. fragment ions undergo gaseous bimol. reaction with the neutral mononuclear complexes to form heavier polynuclear pos. ions, usually with unfragmented ligands. These are analogous to those previously observed for chelates of sterically less hindered β-diketone ligands. Competing with the association reaction in most cases is charge transfer between fragment ions and the neutral complex. Although they prevent intermol. association in condensed phases, the tert-Bu groups on the present complexes hinder, but do not prevent, gaseous ion-neutral association in the tetrahedral and octahedral complexes. No significant hindrance was observed for the planar complexes. The tert-Bu substituents tend also to enhance charge transfer. In the absence of steric hindrance and charge transfer, the tendency to undergo ion-neutral association follows the polarizability or basicity of the ligand. The tendency of the metal to maintain its preferred oxidation state determines which of the possible polynuclear ions will form. These heavy ions are probably Lewis acid-base complexes rather than van der Waals complexes.

The ‘Modified Entrainment Method’ developed by Faktor et al. (1974) is an attractive yet not very popular method to determine vapor pressures in the range of 0.002-0.1 bar at 10-1000°. The method consists of evaporating a solid or liquid from a small bulb through a capillary into a flowing inert gas, e.g. argon. The vapor pressure of the sample is related to the rate of evaporation and some easily controlled exptl. parameters. In the present paper a new convenient exptl. set-up is described and its use to study the decomposition of metal complexes is illustrated.
