This chapter is concerned with a range of ligands that feature sterically encumbering terphenyl substituents. It discusses the syntheses of the bis(terphenyl) main group derivatives M(C6H3‐ 2,6‐Mes2)2 and M(C6H3‐2,6‐Dipp2)2 (M = Ge, Sn, or Pb). The chapter describes synthesis of both H2NC6H3‐ 2,6‐Mes2 and H2NC6H3‐2,6‐Trip2. It provides the synthesi...

On the basis of work with earlier linear two-coordinate metal complexes of the amido [−NAriPr4 and −NAriPr6; AriPr4 = C6H3-2,6(C6H3-2,6-iPr2); AriPr6 = C6H3-2,6(C6H3-2,4,6-iPr3] or aryloxo (−OAriPr4 and −OAriPr6) ligands, it was anticipated that the thiolato ligand −SAriPr4 would also induce linear or near-linear coordination, similar to that in M(...

The titanium bisamido complex Ti{N(H)Ar(iPr6)}2 (Ar(iPr6) = C6H3-2,6-(C6H2-2,4,6-(i)Pr3)2 (2), along with its three-coordinate titanium(III) precursor, TiCl{N(H)Ar(iPr6)}2 (1), have been synthesized and characterized. Compound 1 was obtained via the stoichiometric reaction of LiN(H)Ar(iPr6) with the Ti(III) complex TiCl3·2NMe3 in trimethylamine. Re...

The synthesis and characterization of the first stable two-coordinate vanadium complexes are described. The vanadium(II) primary amido derivative V{N(H)AriPr6}2 [AriPr6 = C6H3-2,6-(C6H2-2,4,6-iPr3)2] (1) was synthesized via the reaction of LiN(H)AriPr6 with the V(III) complex VCl3·2NMe3 or the V(II) salt [V2Cl3(THF)6]+I– in a 2:1 and 4:1 stoichiome...

The mechanism of the reaction of olefins and hydrogen with dimetallenes ArMMAr (Ar = aromatic group; M = Al or Ga) was studied by density functional theory calculations and experimental methods. The digallenes, for which the most experimental data are available, are extensively dissociated to gallanediyl monomers, :GaAr, in hydrocarbon solution, bu...

Reaction of K2COT (COT = 1,3,5,7-cyclooctatetraene, C8H8) with the aryl chromium(II) halide [AriPr4Cr(μ-Cl)]2 (AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) gave (CrAriPr4)2(μ2-η3:η4-COT) (1), in which a nonplanar COT ring is complexed between two CrAriPr4 moieties, a configuration previously unknown for chromium complexes of COT. One Cr2+ ion is bonded prim...

The synthesis and characterization of the mononuclear chromium(II) terphenyl substituted primary amido-complexes Cr{N(H)Ar(Pr(i)(6))}(2) (Ar(Pr(i)(6)) = C(6)H(3)-2,6-(C(6)H(2)-2,4,6-(i)Pr(3))(2) (1), Cr{N(H)Ar(Pr(i)(4))}(2) (Ar(Pr(i)(4)) = C(6)H(3)-2,6-(C(6)H(3)-2,6-(i)Pr(2))(2) (2), Cr{N(H)Ar(Me(6))}(2) (Ar(Me(6)) = C(6)H(3)-2,6-(C(6)H(2)-2,4,6-Me...
