(Texas A&M University. Libraries, 1990)In appropriate solvents at reflux temperatures, anhydrous chromium(III) chloride reacts with the monodentate tertiary phosphines PMe3 and PEt3, and with the bidentate tertiary phosphine, bis(dimethylphosphino)- methane ...
-
(Texas A&M University. Libraries, 1993)Nickel complexes in sulfur-rich environments have been prepared to determine those factors which stabilize organonickel species and permit access to low valent nickel. Nickel tetrathiolate complexes were initially used as ...
-
(Texas A&M University. Libraries, 1989)Synthesis and potentiometric equilibrium studies of the stabilities of the complexes of 1, 3-bis (2', 5;, 8', 11'-tetraaza-undecyl) benzene (MATRIEN) with Cu(II), Co (II), Ni(II), and Zn(II) are reported. Equilibrium ...
-
(Texas A&M University. Libraries, 1983)Heptamethylindenyl complexes of lanthanum, neodymium and erbium containing one, two or three heptamethylindenyl ligands can be synthesized from the reaction of alkali metal heptamethylindenide salts and the appropriate ...
-
(Texas A&M University. Libraries, 1983)The oxidation of 2,6-di-t-butylphenol by molecular oxygen in catalyzed by the (mu)-peroxo dicobalt(III) complexes formed by the ligands tetraethylenepentamine (tetren), 1,4,10,13-tetraaza-7-oxa-tridecane (taotd), ...
-
(Texas A&M University. Libraries, 1989)The multidentate ligand N,N'-ethylenebis[2-(o-hydroxyphenyl)- glycine] (EHPG) contains a mixture of racemic and meso forms of the ligand. Theoretical work has addressed the differences in the stabilities of the meso and ...
-
(Texas A&M University. Libraries, 1982)The synthesis of a series of new binucleating ligands, 1,4-bis(2'-(3''-azapropyl)-2',5'-diazapentyl)benzene (PXBDE), 1,4-bis(2',5',8'-triazaoctyl)benzene (PXBEN), 1,4-bis-(2',5',8',11'-tetraazaundecyl) benzene (PXTRIEN), ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1983)The reactions of VCl(,2)(.)2THF and VCl(,3)(.)3THF with ligands capable of functioning as three atom bridges between metal atoms were studied. Several new dimeric and trimeric vanadium complexes in oxidation states II to ...
-
(Texas A&M University. Libraries, 1991)Synthetic entries into the area of new mono- and dinuclear transition metal complexes containg the tmtaa macrocyclic ligand (where tmtaa = dianion of 5,7,12,14-tetramethyldibenzo[b,i][1,4,8,11] tetraazacyclotetradecine) ...
-
(Texas A&M University. Libraries, 1986)A series of six heterobimetallic carbonyl anions containing Fe and group 6 metals have been synthesized and characterized by spectroscopic techniques, chemical reactivity, and X-ray crystallography. The structural features ...
-
(Texas A&M University. Libraries, 1990)New convenient synthetic routes into mononuclear and dinuclear transition metal complexes with the ligand α-carboline are described. In addition, a new high yield preparative route for α-carboline is presented. Several ...
