tert-Butylimino-δ-Organovanadium(V)-Verbindungen Darstellung und NMR-spektroskopische Untersuchungen/tert-Butylimino-δ-Organovanadium (V) Compounds Synthesis and NMR Spectroscopic Studies

Abstract

The compounds ^tC₄H₉N=VR(O^tC₄H₉)₂ (R = CH₃, ⁿC₄H₉, CH₂SiMe₃, Mes) and ^tC₄H₉N = VMes₂(O^tC₄H₉) have been prepared by reaction of tert-butyliminovanadium (V) chlorides with LiR; ^tC₄H₉N=V(CH₂SiMe₃)₂(O^tC₄H₉) and ^tC₄H₉N=VR₃ (R = CH₂SiMe₃, Mes) could only be characterized by NMR spectroscopy. The ¹H, ¹³C and ⁵¹V NMR spectra are discussed; the constants of ⁵¹V , ¹⁴N coupling have been determined.
