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(OtC4H9)2 (R = CH3, nC4H9, CH2SiMe3, Mes) and tC4H9N = VMes2(OtC4H9) have been prepared by reaction of tert-butyliminovanadium (V) chlorides with LiR; tC4H9N=V(CH2SiMe3)2(OtC4H9) 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.
