The reaction of vinyl chloride (VC) with (α-diimine)PdMe+ species yields (α-diimine)PdCl(propene)+. Isotope labeling experiments using the deuterium-labeled vinyl chlorides 1-VC-d1 and Z-VC-d1 combined with DFT computations establish that this reac

The generation and properties of the Cp2Zr{CH(SiMe3)2}+ cation are described. An X-ray crystallographic analysis shows that the carborane salt [Cp2Zr{CH(SiMe3)2}][HCB11Me5Br6] contains an agostic Zr–μ-Me–Si interaction in the solid state. Low te

Addition of alkynes to [Cp‘2Zr(OtBu)][B(C6F5)4] (Cp‘ = C5H4Me, 2) at low temperature in CD2Cl2 solution yields equilibrium mixtures of Cp‘2Zr(OtBu)(RC⋮CR‘)+ (3a−g), 2, and free alkyne. The 13C NMR ...

(EtMe2SiC5H4)CpZrCl2 (5) reacts with BBr3 in 1,2-dichloroethane (reflux, 24 h) to afford a 4:1 mixture of (EtMeBrSiC5H4)CpZrBr2 (10) and (BrMe2SiC5H4)CpZrBr2 (11) in a nearly quantitative conversion. Similarly, (tBuMe2SiC5H4)CpZrCl2 (6) reacts with B

This paper describes the generation and properties of nonchelated d(0) zirconocene-aryl-alkene and alkyne adducts that are stabilized by the presence of beta-SiMe(3) substituents on the substrates and the weak nucleophilicity of the -C(6)F(5) ligand.

The generation and properties of nonchelated Zr-aryl-alkyne and Zr-aryl-alkene complexes that are stabilized by the presence of beta-Si-substituents in the alkyne and alkene ligands and fluorination of the aryl ligand are described. Reaction of [Cp'2

This paper describes the synthesis of base-free (C5R5)2Zr(OtBu)+ cations, the direct observation of nonchelated alkene and alkyne adducts of these cations, and studies of the thermodynamic and dynamic properties of these novel species. Reaction of %@
