Alkylvanadium(V)-Verbindungen Darstellung und NMR-spektroskopische Untersuchungen/Alkylvanadium(V) Compounds Synthesis and NMR Spectroscopic Studies
1982
Zeitschrift für Naturforschung. B, A journal of chemical sciences
The compounds Li[nC4H9VO(OtC4H9)3], Me3SiCH2V(OtC4H9)3, (CH3)2V(OSiMe3)2 and V(OtC4H9)4 have been prepared by reaction of esters VO(OR)3(R = tC4H9, SiMe3) with lithium alkyls. RVO(OtC4H9)2 species are not formed by direct alkylation of VO(OtC4H9)3 with LiR; albeit in small yields, these compounds (R = CH3, CH2SiMe3) can be synthesized however from VO(OtC4H9)2Cl. The 51V, 1H and 13C NMR spectra of the vanadium(V) and vanadium(IV) compounds are discussed; the constants of 51V, 1H and 51V, 13C coupling have been determined.
