Ansa-zirconocene complexes are widely employed as precatalysts for olefin polymerization. Their synthesis generally leads to mixtures of their rac and meso isomers, whose separation is often problematic. In this contribution, we report on the synthes

Formation and C–F bond functionalization of [P,N]-ligated perfluoronickelacyclopentanes

Autor: R. Tom Baker, Ilia Korobkov, Kaitie A. Giffin, Lorraine A. Pua

Publikováno v: Polyhedron. 157:458-466

Detailed herein is the synthesis and characterization of [P,N]-ligated perfluoronickelacyclopentanes based on the bidentate ligand 2-(diphenylphosphino)phenyl-N-phenylaniline [P,NH]. A high-yielding substitution reaction between [P(O-o-tol)3]2Ni(C4F8

Generation of Hydrofluoronickelacycles from Trifluoroethylene and Ni(0): Ligand Effects on Regio-/Stereoselectivity and Reactivity

Treatment of Ni(0) complexes 1a–e with sub-atmospheric pressures of trifluoroethylene (TrFE) affords hydrofluoronickelacyclopentanes L2Ni(C4F6H2) 2a–e (L = PPh3, P(O-o-tol)3, PPh2Me, PPhMe2, PMe3). Fluorine NMR analysis of 2a–e demonstrates pre

Brønsted acid-promoted C–F bond activation in [P,S]-ligated neutral and anionic perfluoronickelacyclopentanes

Autor: Ilia Korobkov, Kaitie A. Giffin, R. Tom Baker

Publikováno v: Dalton Transactions. 44:19587-19596

Treatment of L2Ni(CF2)44a-c (L = PPh3, PPh2Me, pyridine) with an external Lewis acid (trimethylsilyl triflate) gives new L-functionalized fluoronickelacyclopentanes 5a-c. Complexes L2Ni(CF2)44a,b react with the thiol form of the bidentate ligand 1,2,

Activation of C–F and Ni–C Bonds of [P,S]-Ligated Nickel Perfluorometallacycles

Autor: R. Tom Baker, Daniel J. Harrison, Ilia Korobkov, Kaitie A. Giffin

Publikováno v: Organometallics. 32:7424-7430

The first example of a [P,S]-ligated metal perfluorocyclopentane is reported. The new metallacycle undergoes Cα–F activation in the presence of a Lewis acid, followed by chemoselective ligand migration, affording a fused metallabicyclic product. R
