  A series of zirconocenes L2ZrCl2 (23 examples) were studied as catalysts in the reaction of alkenes with AlEt3. The catalyst activity and reaction chemoselectivity were found to depend on the ligand structure in the complex and the nature of the solvent. The alkyl exchange in the triethylaluminum dimer was studied by NMR spectroscopy; a solvent effect on the alkyl exchange parameters was established

  structures, as well as solvent, affect the overall yield and enantiomeric excess of the reaction product - 3-alkylsubstituted aluminacyclopentanes. The reaction of terminal alkenes with AlEt3, catalyzed by complex 1, in hydrocarbon solvents gives predominantly S-enantiomers of cyclic organoaluminum compounds with enantiomeric excess up to 37%.

• New effective reagent [Cp2ZrH2·ClAlEt2]2 for alkene hydrometallation

  New bimetallic complex [CP2ZrH2 . ClAlEt2](2) (1) was synthesized, and its reactivity in hydrometallation reaction with the following alkenes was studied: hept-l-ene, okt-l-ene, alpha-methylstyrene, (IS)-beta-pinene, (+)-camphene. Complex 1 shows the highest reactivity among the other known AI,Zr-bimetallic complexes: [CP2ZrH2 . ClAlBu2i](2) (2), [CP2ZrH2 . AlEt3](2) (3), [CP2ZrH2 . AlBu3i](2) (4) and [CP2ZrH2 . HAlBu2i] (5) as well as organoaluminium compounds (OAC): (BU2AlH)-B-i, (Bu3Al)-Bu-i and (Bu2AlCl)-Bu-i in presence of Zr catalysts. Chlorine containing complexes 1 and 2 appear to be more effective in alkene hydrometallation, and relative hydrometallation rates are (1S)-beta-pinene <= (+)-camphene < alpha-methylstyrene < oct-l-ene < hept-l-ene. Hydrometallation of (1S)-beta-pinene and its subsequent oxidation with 12 run with high diastereoselectivity and yield trans-myrtanol. However, the diastereoselectivity of (+)-camphene hydrometallation is less than that for (1S)-beta-pinene, and the reaction gives predominately endo-camphanol. (c) 2007 Elsevier B.V.
