The synthesis and properties of some new metallodibenzotetraaza[14]annulenes
(1978)
Several new metallodibenzotetraaza[14]annulenes have been prepared that exhibit unique coordination chemistry. The ligands utilized in these new complexes are 1,8-dihydrodibenzo(b,i)(1,4,8,11)tetraaza[14]-annulene (C₁₈H₁₆N₄ ...
A study of the cobalt (II) chloride-acetonitrile system by vapor pressure osmometry and visible absorption spectroscopy
(1970)
In recent years, independent investigators have studied the anhydrous system composed of cobalt(II) chloride and acetonitrile and have arrived at results which appear to be somewhat ambiguous. G. J. Janz and co-workers ...
Spectrochemical studies of coordination complexes: I. Stereospecific kinetics of the ligand-ligand exchange reactions of D*-(-)- and L*-(+)-1,2-propylenediaminetetraacetatolead (II) with D-(-)-trans-1,2-cyclohexanediaminetetraacetic acid
(1972)
The ligand-ligand exchange reactions of D-(-)-trans-1,2-cyclohexanediaminetetraacetic acid (D(-)CDTA) with D*-(-)-[Pb(L(+)PDTA)] and L*-(+)-[Pb(D(-)PDTA)] (PDTA denotes 1,2-propylenediaminetetraacetic acid) over the pH ...
The extraction of mineral acids and transition metal ions by Di(n-octyl) arsinic acid (DOAA) in chloroform
(1972)
The extraction of HClO₄, HCl, HBr, HNO₃, H₂SO₄, HI and the metal ions SC(III) in HCl solution, Ce(III), Eu(III), Ho(III) and Yb(III) in acetate buffered solutions by chloroform solutions of diocytlarsinic acid (DOAA), ...
The determination of trace levels of oxygen and carbon by charged particle activation analysis
(1969)
Research and development in ultrapure materials require analytical methods with sensitivities in the part per million to part per billion range for many of the light elements. Current analytical methods are of limited ...
A study of some haloferrate complexes and a potentiometric equilibrium study of the ferric chloride system
(1965)
Several chloroferrate(III) and bromoferrate(III) salts of aliphatic and aromatic amines have been prepared and isolated. The chemical compositions, based on iron and chloride analyses, have been compared with theoretical ...
Physical properties of some binuclear copper (II) complexes
(1969)
The copper(II) complexes of citric acid and N,N'-diglycylethyl-enediamine have been studied in aqueous solutions in the pH range 2 to 10 electron spin resonance, nuclear magnetic resonance, optical spectrophotometry, and ...
Magnetic and asymmetric induced circular dichroism studies of polymers
(1972)
The magnetic circular dichroism (MCD) spectra of syndiotactic and isotactic polymers containing aromatic chromophores have been found sensitive to subtle configurational and conformational differences. For isotactic polymers ...
Highly substituted cyclohexanones and bicyclic derivatives: synthesis, structure and NMR studies
(1970)
A new family of 3-aryl-3,5,5-trisubstituted cyclo-hexanones have been synthesized and studied by proton and carbon-13 NMR spectroscopy, [diagram and equation on PDF]. These highly substituted ketones have been prepared by ...
