| Popis: | Polymer-attached CpNbCl 4 , CpNbCl 3 , CpNbCl 2 , Cp 2 Nb(BH 4 ), CpTaCl 4 , (PhCH 2 )NbCl 4 and (PhCH 2 )TaCl 4 have been prepared. The reduction products of supported niobium and tantalum chlorides are active hydrogenation catalysts for olefins and for diphenylacetylene which was hydrogenated to 1,2-diphenylethane through intermediate stilbene. The similar reduction products have also been employed in catalytic isomerization of allylbenzene which is converted into a mixture of trans - and cis -propenylbenzene. Polymer-attached CpTaCl 4 , when treated with neopentyllithium, can effect dimerization of ethylene to give 1-butene. |
