Low-Coordinate (Arylimido)vanadium(V) Alkyls: Synthesis and Reactivity of V(NAr)(CH 2 Ph) 3 (Ar = C 6 H 3 -2,6-Pr i 2 )

The syntheses of a series of stable vanadium(V) alkyls have been achieved by the support of arylimido ligation. The (arylimido)vanadium(V) tribenzyl complex V(NAr)(CH 2 Ph) 3 (Ar = C 6 H 3 -2,6-Pr i 2 ) has been prepared in high yield by the treatment of V(NAr)Cl 3 ·THF with PhCH 2 MgCl. This compound, which represents the first structurally characterized vanadium(V) trialkyl complex, is a valuable synthetic precursor to a series of other vanadium(V) dialkyl derivatives with supporting alkoxide, aryloxide, and amido functionalities.
