Electron-deficient group IV metal alkyl cations, and the synthesis of Zr(CH2Ph)3(η6-C6H5)BPh3: a fluxional arene π-complex of a d0 metal
Abstract
Mild protolysis of titanium and zirconium alkyls provides a general route to solvent or anion stabilised 6- and 10-electron cationic group IV alkyl complexes, including the first halide-free arene complex of a d0 metal.
