Title: CO₂ conversion to phenyl isocyanates by uranium(vi) bis(imido) complexes

Abstract

U( vi ) trans -bis(imido) complexes [U(κ ⁴ {( ^tBu2 ArO) ₂ Me ₂ -cyclam})(NPh)(NPh ^R )] react with CO ₂ to afford U( vi ) trans -[OUNR] ²⁺ complexes with elimination of isocyanates. These are unprecedented examples of CO ₂ cleavage mediated by U( vi ) imido complexes.

Multiple-imido complexes of molybdenum: Synthesis and reactivity of the d{sup 0} Mo(=NR){sub 3} functional group

Journal Article Morrison, D L ; Wigley, D E - Inorganic Chemistry

Red-orange crystals of the tris(imido) anion of molybdenum, [Mo(NAr){sub 3}Cl]{sup {minus}} (3, Ar=2,6-C{sub 6}H{sub 3}-i-Pr{sub 2}) are isolated as the [Li(THF){sub 4}]{sup +} salt from the rapid workup of the reaction between Mo(NAr){sub 2}Cl{sub 2}(THF){sub 2} (1) and 2 equiv of LiNHAr (in THF). [Li(THR){sub 4}][Mo(NAr){sub 3}Cl] (3) constitutes the kinetic product of this reaction since it readily reacts with byproduct H{sub 2}NAr to afford stable Mo(NAr){sub 2}(NHAr){sub 2} (4). Complex 3 undergoes nucleophilic attack by PMe{sub 3}, MeLi, Me{sub 3}CCH{sub 2}Li, or Br{sup {minus}} to form Mo(NAr){sub 3}(PMe{sub 3}) (5), [Li(THF){sub 4}][Mo(NAr){sub 3}Me] (6), [Li(THF){sub 4}]-[Mo(NAr){sub 3}(CH{sub 2}CMe{sub 3})]more »« less

Organorhenium imido complexes: Synthese, structure, and reactivity

Journal Article Herrmann, W A ; Weichselbaumer, G ; Paciello, R A ; ... - Organometallics; (USA)

Imido complexes of heptavalent rhenium have been synthesized by three different routes: (i) aminolysis of the half-sandwich complex ({eta}{sup 5}-C{sub 5}Me{sub 5})ReCl{sub 4} (1) (Me = CH{sub 3}) with primary amines gives the imidoderivatives ({eta}{sup 5}-C{sub 5}Me{sub 5})Re(N{sup t}Bu)Cl{sub 2} (2a, {sup t}Bu = tert-butyl) and ({eta}{sup 5}-C{sub 5}Me{sub 5})Re(NCH{sub 3})Cl{sub 2} (2b). The rhenium-nitrogen distance in compound 2a (1.709 (3) {angstrom}) corresponds to a triple bond (single-crystal X-ray diffraction), while the analogous oxo congener ({eta}{sup 5}-C{sub 5}Me{sub 5})ReOCl{sub 2} has relatively little rhenium-oxygen triple-bond character.

Insertion of CO/sub 2/-like molecules into zirconium-carbon bonds: reactivity of dialkylbis(cyclopentadienyl)zirconium(IV) with diphenylketene, aryl isocyanates, and p-tolycarbodiimide

Journal Article Gambarotta, S ; Strologo, S ; Floriani, C ; ... - Inorg. Chem.; (United States)

Diphenylketene, aryl isocyanates, and p-tolylcarbodiimide insert into Zr-C bonds of (cp)/sub 2/ZrR/sub 2/ (cp = eta/sup 5/-C/sub 5/H/sub 5/; R = Me(I), PhCH/sub 2/(II), Ph(III). The insertion of the >C=O unit diphenylketene into the Zr-R bond gives )(cp)/sub 2/Zr(R)(O-C(R)=CPh/sub 2/)) complexes (II), which add a further molecule of diphenylketene to form ((cp)/sub 2/Zr(O-C(R)=CPh/sub 2/)/sub 2/). The vinyl-oxo ligand has normal structure characteristics, and the C=C bond does not interact with the metal. Reaction of isocyanates (ArNCO) with complexes (I-III) led to the formation of an imido ligand bonding the metal in a bidentate fashion. Analogous results have been obtained bymore »« less

Uranium (VI)Bis(imido) chalcogenate complexes:synthesis and density functional theory analysis

Journal Article Spencer, Liam P ; Batista, Enrique R ; Boncella, James M ; ... - Inorganic Chemistry

Bis(imido) uranium(VI) trans- and cis-dichalcogenate complexes with the general formula U(NtBu)2(EAr)2(OPPh3)2 (EAr = O-2-tBuC6H4, SPh, SePh, TePh) and U(NtBu)2(EAr)2(R2bpy) (EAr = SPh, SePh, TePh) (R2bpy = 4,4'-disubstituted-2,2'-bipyridyl, R = Me, tBu) have been prepared. This family of complexes includes the first reported monodentate selenolate and tellurolate complexes of uranium(VI). Density functional theory calculations show that covalent interactions in the U-E bond increase in the trans-dichalcogenate series U(NtBu)2(EAr)2(OPPh3)2 as the size of the chalcogenate donor increases and that both 5f and 6d orbital participation is important in the M-E bonds of U-S, U-Se, and U-Te complexes.
