Cyclopentane carboxylate compounds, process and intermediates for preparing the same and use thereof

摘要

The present invention discloses cyclopentane carboxylate compounds. The 1-hydrocarbyl-2-acyloxy-cyclopentane carboxylates according to the invention have a general formula (I): wherein groups R¹, R² and R³, which are identical or different, are independently selected from the group consisting of linear or branched C₁-C₂₀alkyl, C₃-C₂₀cycloalkyl, C₆-C₂₀aryl, C₇-C₂₀alkaryl and C₇-C₂₀aralkyl. The present invention also discloses a process as well as intermediate compounds for preparing the compounds of formula (I), and use of the compounds (I) as electron donor in the preparation of catalysts for propylene polymerization.
