  Catalytic synthesis and transformations of magnesium-cycloalkanes. 1. New catalytic transformations in the series of magnesium-cyclopentanes

  摘要：

  The reactions of magnesium-cyclopentane with styrene and of 2,4-diphenylmagnesium-cyclopentane with ethylene in the presence of catalytic amounts of Cp2ZrCl2 leading to the formation of 2-phenylmagnesium-cyclopentane and 2,4-diphenylmagnesium-cycloheptane, were studied for the first time. It was found that ziroconocyclopentanes, are intermediates in this reaction, which are formed both from magnesium-cycloalkanes and from alpha-olefins and Cp2ZrCl2. A possible mechanism of the reactions studied has been proposed.
