Title: Lutetium functionalities supported by a sterically encumbered β-diketiminate ligand

Abstract

The sterically encumbered NacNac ligand, [HC(MeCNAr) ₂] ^– (Ar = 2,6- i-Pr ₂C ₆H ₃), was investigated as a platform for supporting Lu-halide complexes, sought for their potential capability of being further converted into hydrocarbyl derivatives via metathetical chemistries with alkali metal alkyls. As a result, these substituted analogs were targeted as potentially viable candidates for alkane elimination chemistries, with an eye towards the formation of an isolable Lu-alkylidene fragment.

This contribution describes lutetium and yttrium hydrocarbyl and hydride chemistry based upon the chelating R{sub 2}Si({eta}{sup 5}-C{sub 5}H{sub 4})({eta}{sup 5}-Me{sub 4}C{sub 5}){sup 2{minus}} ligand (R = Me, Et; abbreviated R{sub 2}SiCpCp{double prime}). The ligand is prepared by reaction of the corresponding R{sub 2}Si(CP{double prime})Cl derivative with NaC{sub 5}H{sub 5}. Subsequent metalation and reaction with MCl{sub 3}{center dot}3THF (M = Y, Lu) yields R{sub 2}SiCpCp{double prime}MCl{sub 2}{sup {minus}}Li(OEt{sub 2}){sub 2}{sup +} complexes, which in turn can be alkylated to yield R{sub 2}SiCpCp{double prime}MCHTMS{sub 2} derivatives (TMS = SiMe{sub 3}).

Catalytic activity of a series of Zn(II) phenoxides for the copolymerization of epoxides and carbon dioxide

Journal Article Darensbourg, D.J. ; Holtcamp, M.W. ; Struck, G.E. ; ... - Journal of the American Chemical Society

A series of zinc phenoxides of the general formula (2,6-R{sub 2}C{sub 6}H{sub 3}O){sub 2}Zn(base){sub 2} [R = Ph, {sup t}Bu, {sup i}Pr, base = Et{sub 2}O, THF, or propylene carbonate] and (2,4,6-Me{sub 3}C{sub 6}H{sub 2}O){sub 2}Zn(pyridine){sub 2} have been synthesized and characterized in the solid state by X-ray crystallography. All complexes crystallized as four-coordinate monomers with highly distorted tetrahedral geometry about the zinc center. The angles between the two sterically encumbering phenoxide ligands were found to be significantly more obtuse than the corresponding angles between the two smaller neutral base ligands, having average values of 140{degree} and 95{degree}, respectively.

Reaction of 3 equiv of 2,6-diisopropylphenol with Ln[N(SiMe{sub 3}){sub 2}]{sub 3}(Ln=Nd, Sm, Er) in refluxing toluene and subsequent crystallization yield pale blue (Nd), deep yellow (Sm), or light pink (Er) crystals of the tris(aryloxide) complexes Ln{sub 2}(O-2,6-i-Pr{sub 2}C{sub 6}H{sub 3}){sub 6}(Ln = Nd(1), Sm(2), Er(3)) in good yield. X-ray crystallographic studies of 1 and 2 reveal centrosymmetric, dimeric units bridged by {eta}{sup 6}-{pi}-arene interactions of a unique aryloxide ligand. Ln-O bond lengths average 2.122(9) (1,Nd) and 2.101(6) {Angstrom} (2,Sm) for terminal ligands and 2.211(8) (1) and 2.198(5) {Angstrom} (2) for bridging aryloxide ligands. {eta}{sup 6}-Arene bridges hold the dimeric unitsmore »« less

Journal Article Pagano, Justin K. ; Arney, David S. J. ; Scott, Brian L. ; ... - Dalton Transactions

Here, three new uranium species (C ₅Me ₅) ₂U(=N-2,6- ⁱPr ₂-C ₆H ₃)(=S), (C ₅Me ₅) ₂U(=N-2,6- ⁱPr ₂-C ₆H ₃)(η ²-S ₂), and (C ₅Me ₅) ₂U(=N-2,6- ⁱPr ₂-C ₆H ₃)(S=PMe ₃) were synthesized and fully characterized by a combination of NMR, IR, and UV/vis–NIR spectroscopies, elemental analysis, and cyclic voltammetry. The solid state structures of (C ₅Me ₅) ₂U(=N-2,6- ⁱPr ₂-C ₆H ₃)(=S) and (C ₅Me ₅) ₂U(=N-2,6- ⁱPr ₂-C ₆H ₃)(η ²-S ₂) were also determined.

Journal Article Lichtscheidl, Alejandro Gaston ; Pagano, Justin K. ; Scott, Brian Lindley ; ... - Inorganics

The organometallic uranium species (C ₅Me ₄R) ₂UBr ₂ (R = Me, Et) were obtained by treating their chloride analogues (C ₅Me ₄R) ₂UCl ₂ (R = Me, Et) with Me ₃SiBr. Treatment of (C ₅Me ₄R) ₂UCl ₂ and (C ₅Me ₄R) ₂UBr ₂ (R = Me, Et) with K(O-2,6- ⁱPr ₂C ₆H ₃) afforded the halide aryloxide mixed-ligand complexes (C ₅Me ₄R) ₂U(O-2,6- ⁱPr ₂C ₆H ₃)(X) (R = Me, Et; X = Cl, Br). Complexes (C ₅Me ₄R) ₂U(O-2,6- ⁱPr ₂C ₆H ₃)(Br) (R = Me, Et) can also be synthesized by treating (C ₅Me ₄R) ₂U(O-2,6-more »« less
