<jats:title>Abstract</jats:title> <jats:p> <jats:sup>1</jats:sup>C<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>N = V(OSiMe<jats:sub>3</jats:sub>)<jats:sub>3</jats:sub> has been prepared by reaction of NH<jats:sub>4</jats:sub>VO<jats:sub>3</jats:sub> with HNSiMe<jats:sub>3</jats:sub>(<jats:sup>t</jats:sup>C<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>). This compound is the starting material for the synthesis of C<jats:sub>6</jats:sub>H<jats:sub>5</jats:sub>N = V(OSiMe<jats:sub>3</jats:sub>)<jats:sub>3</jats:sub> and <jats:sup>t</jats:sup>G<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>N = VCl<jats:sub>3</jats:sub> by transamination with aniline or redistribution with VOCl<jats:sub>3</jats:sub>, respectively. The properties of the trichloride are studied by chemical reactions such as redistribution, complex formation and substitution with silver carboxylates. All compounds are mono-meric in solution, probably containing a nitrogen vanadium triple bond.
