A series of water-soluble molecular cobalt complexes of tetraazamacrocyclic ligands are reported for the electrocatalytic production of H(2) from pH 2.2 aqueous solutions. The comparative data reported for this family of complexes shed light on their relative efficiencies for hydrogen evolution in water. Rotating disk electrode voltammetry data are presented for each of the complexes discussed,...

The condensation reaction between dimethylglyoxime, acetic acid, and 4-aminophenol was significantly influenced by the [LH2] type donor derivative ligand. conducted in methanol for 24 hours while being stirred refluxed. syntheses forming a new (2E,3E)-butane-2,3-dione O2-((E)-1-((4-hydroxyphenyl)imino)ethyl) O3-((Z)-1-((4-hydroxyphenyl)imino)ethyl) dioxime) dioxime ligand [LH2]. Spectroscopic t...

p-Quinone dioxime, a rubber vulcanization accelerator, was selected for bioassay by the National Cancer Institute because of a lack of adequate carcinogenicity data. A bioassay for the possible carcinogenicity of p-quinone dioxime was conducted using Fischer 344 rats and B6C3F1 mice. p-Quinone dioxime was administered in the feed, at either of two concentrations, to groups of 50 male and 50 fem...

A trinuclear nickel complex of phenanthrene-9,10-dione dioxime (H2pqd), namely bis-[μ2-9,10-bis-(oxido-imino)-phenanthrene]-bis-[μ2-10-(oxido-imino)phenanthrene-9-one oxime](phenanthrene-9,10-dione dioxime)trinickel(II) toluene disolvate, [Ni3(C14H8N2O2)2(C14H9N2O2)2(C14H10N2O2)]·2C7H8, has been isolated and its crystal structure determined. This complex features three independent Ni(II) atoms ...
