The aminovanadium(V) compounds VO(OR)2 and VO(OR)2 have been prepared by reaction of LiNR'(SiMe3) with VO(OR)2Cl and VO(OR)Cl2, respectively; their spectroscopical data (1H NMR, IR, MS) are reported.All compounds are monomeric in solution.In some cases 1.3 migration of SiMe3 groups from nitrogen to oxygen is observed on heating.Kinetic measurements indicate the rearrangement reaction to be irreversible and intramolecular.The reaction of VO(OR)Cl2 with HNR'(SiMe3) leads to iminovanadium(V) compounds such as R'N=V(OSiMe3)3, R'N=V(OSiMe3)2(OR) and R'N=V(OR)2Cl. - Keywords: Amino and Iminovanadium(V) Compounds, Preparation, Spectroscopical Characterisation, Kinetics
