  On study of chemoselectivity of reaction of trialkylalanes with alkenes, catalyzed with Zr π-complexes

  摘要：

  The influence of the organoaluminium compound nature, Zr p-ligand environment, solvent type and reagent ratio on the chemoselectivity of reactions of trialkylalanes (AlMe3, AlEt3) with alkenes, catalyzed with L2ZrCl2 [L = Cp, Cp' (Cp'-eta(5)-C5H4CH3), Cp* (Cp*-eta(5)-C-5(CH3)(5)), Ind (indenyl), Flu (fluorenyl)] has been studied. It is shown that in the case of AlMe3, the hydro-and carboalumination products, and alkene dimers are formed. The catalytic reaction of AlEt3 with the olefins yields aluminacyclopentanes altogether with the hydro-and carboalumination products, and the dimers. A probable reaction mechanism has been proposed.

  and enantioselectivity. The reaction chemo- and enantioselectivity depend on the catalyst structure and reaction conditions (solvent type, catalyst concentration, temperature) as well. It is shown that the lack of asymmetric induction in the reaction of α-methylstyrene hydroalumination by HAlBu2i, catalyzed with complexes 1 or 3, is the result of the formation of Zr hydride complexes of different structures
