- W2078609511 abstract "Die Reaktion des Zirconocendichlorids mit zwei Äquivalenten n-Butyllithium und Trimethylphosphan liefert (1-Buten)(trimethylphosphan)zirconocen (1) in 83 proz. Ausbeute. Komplex 1 ist ein ausgezeichnetes Ausgansmaterial zur Darstellung weiterer (Alken)- oder (Alkin)zirconocen-Komplexe; so erhält man durch Verdrängung des 1-Butens mit Ethylen, Styrol oder Tolan die Zirconocen-Komplexe 2, 3 oder 7 in hohen Ausbeuten. Eine weitere Darstellungsmethode für (1-Alken)(trimethylphosphan)zirconocen-Komplexe ist die Umsetzung von Zirconocendichlorid mit 1-Alkylmagnesiumhalogeniden in Gegenwart von Trimethylphosphan bei Raumtemperatur; z. B. sind so der 1-Propen-Komplex 9 und der 1-Penten-Komplex 10 gut zugänglich. Spektroskopische Untersuchungen (1H-, 13C- und 31P-NMR) zeigen, daß alle dargestellten (1-Alken)(trimethylphosphan)zirconocen-Komplexe in Lösung bei 0°C als getrennt beobachtbare Rotamerenpaare 1a, b, 3a, b, 9a, b und 10a, b im Verhältnis ca. 4:1 vorliegen. Die Strukturen des Ethylen-Komplexes 2 und des Styrol-Komplexes 3a wurden zusätzlich durch Kristallstrukturanalysen ermittelt. 1-Alkene)trimethylphosphine)zirconocenes: Preparation, Characterization, and Reactivity (1-Butene)(trimethylphosphine)zirconocene (1) is prepared in 83% yield by subsequent reaction of zirconocene dichloride with two equivalents of n-butyllithium and trimethylphosphine. Reaction of complex 1 with other alkenes or alkynes, e.g. ethylene, styrene, or tolane indicates that this compound is an ideal starting material for synthezising other (alkene)- or (alkyne)zirconocene complexes, e.g. 2, 3, or 7. Another route to (1-alkene)(trimethylphosphine)zirconocenes, e.g. the 1-propene complex 9 or the 1-pentene complex 10, is the reaction of zirconocene dichloride with 1-alkylmagnesium halide in the presence of trimethylphosphine at room temperature. Spectroscopic investigations 1H-, 13C-, and 31P-NMR spectroscopy) confirm that in solution, complex 1 as well as the other 1-alkene complexes 3, 9, and 10 exist as a mixture of two rotamers 1a, b, 3a, b, 9a, b, and 10a, b in a ca. 4:1 ratio. The structures of the ethylene complex 2 and the styrene complex 3a are also determined by X-ray analyses." @default.
