Abstract

A complex containing a V-Al bond is described. This species can be prepared by either transmetallation of a previously disclosed alumanylpotassium with Cp2VCl or photolytic oxidative alumi-nation of Cp2V using the corresponding dialumane(4). Reaction of the resulting V-Al complex with H2 gave a Cp2V-dihydridoaluminate complex. These complexes were studied with X-ray crystallography, spectroscopy including 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.
