| Popis: | The thermal decomposition of some dialkylbis(η 5 -cyclopentadienyl)metals in pentane and toluene solutions at 60°–80 °C have been studied. The metals were Ti, Zr, Hf, Nb, Ta, Mo, and W. The alkyls were n-propyl, n-butyl, n-amyl, neopentyl, and neohexyl. Dineopentylbis(η 5 -pentamethylcyclopentadienyl)titanium was also studied. In addition to the expected alkanes and alkenes, some methane, ethylene, and other hydrocarbons were obtained. The formation of these minor products is rationalized on the basis of δ- and γ-hydrogen elimination and metal carbene formation. A metallacyle pathway probably follows the hydrogen abstraction. Reproducible quantities of the products were obtained. |
