The VCl3/Al/AlCl3/mes (mes = 1,3,5-Me3C6H3) system gives, after treatment with THF, the bismesitylenevanadium(I) tetrachloroaluminate, [V(eta-6-1,3,5-Me3C6H3)2]AlCl4, [Vmes2]AlCl4, the structure of which has been determined by an X-ray diffraction study. The crystal consists of the discrete AlCl4- and [Vmes2]+ ions, the former tetrahedral and the latter having eclipsed arene ligands. The iodide [Vmes2]I is reduced by biscyclopentadienylcobalt(II), CoCp2, in THF in excellent yields.

Abstract
The VCl3/Al/AlCl3/mes (mes = 1,3,5-Me3C6H3) system gives, after treatment with THF, the bismesitylenevanadium(I) tetrachloroaluminate, [V(eta-6-1,3,5-Me3C6H3)2]AlCl4, [Vmes2]AlCl4, the structure of which has been determined by an X-ray diffraction study. The crystal consists of the discrete AlCl4- and [Vmes2]+ ions, the former tetrahedral and the latter having eclipsed arene ligands. The iodide [Vmes2]I is reduced by biscyclopentadienylcobalt(II), CoCp2, in THF in excellent yields.File in questo prodotto:
