Vanadium Alumanyl Complex: Synthesis, Characterization, Reactivity, and Application as a Catalyst for C-H Alumanylation of Alkenes.

A complex containing a V-Al bond is described. This species can be prepared by either transmetalation of a previously disclosed alumanylpotassium with Cp 2 VCl or photolytic oxidative alumination of Cp 2 V using the corresponding dialumane. Reaction of the resulting V-Al complex with H 2 gave a Cp 2 V-dihydridoaluminate complex. These complexes were studied with X-ray crystallography, vanadium K -edge XANES spectroscopy, and DFT calculations. Finally, the reactivity of these molecules was studied opening the way to a catalytic C-H alumanylation of alkenes.
