Description
Orthovanadic acid esters react with dimethyl zinc to methyl vanadium oxide dialkoxides, CH3VO(OR)2. The reaction rate and the thermal stability of organovanadium compounds formed depend on the structure of the alkyl groups. The pure compounds with R = CH(CH3)2, CH(CH3)C2H5 and C(CH3)3 are isolated and characterized. Vanadium tetraalkoxides react with zinc dialkyls in a similar way. The intermediat alkyl vanadium trialkoxides, RV(OR')3 undergo a reductive decomposition already at deep temperatures. (author)
Abstract (German)
Orthovanadinsäureester reagieren mit Zinkdimethyl zu Methylvanadin‐oxid‐dialkoxiden, CH 3 VO(OR) 2 . Die Reaktionsgeschwindigkeit und die thermische Stabilität der entstehenden Organovanadinverbindungen hängt weitgehend vom sterischen Bau der Alkoxidreste ab. In reiner Form wurden die Verbindungen mit R = CH(CH 3 ) 2 , CH(CH 3 )C 2 H 5 und C(CH 3 ) 3 erhalten und charakterisiert. Vanadin(IV)‐alkoxide reagieren mit Zinkdialkylen auf ähnliche Weise. Die primär entstehenden Alkylvanadintrialkoxide, RV(OR′) 3 unterliegen jedoch bereits bei tiefer Temperatur einem reduktiven Zerfall.Additional details
