Synthesis of substituted amidobenzoate compounds, the compounds obtained and the use thereof as phthalate free internal electron donor for polymerization of olefins

Abstract

The present invention relates to a compound according to Formula (I) wherein Ris a hydrocarbyl group selected from the group consisting of alkyl, alkenyl, aryl, aralkyl, and alkylaryl groups, and one or more combinations thereof; wherein Ris a hydrogen atom, an aryl group or an alkyl group; and wherein R, R, Rand R, are the same or different and are each independently a hydrogen atom, a halogen atom, a cyano group, an amino group, a hydrocarbyl group selected from the group consisting of alkyl, alkenyl, aryl, aralkyl, and alkylaryl groups or an alkoxy group, and one or more combinations thereof as internal electron donor and to a process for the synthesis of a compound according to Formula (I), wherein Ris a hydrocarbyl group selected from the group consisting of alkyl, alkenyl, aryl, aralkyl, alkoxycarbonyl and alkylaryl groups, and one or more combinations thereof; wherein Ris a hydrogen atom or an alkyl group; wherein R, R, Rand R, are the same or different and are each independently selected from a group consisting of a hydrogen atom; a hydrocarbyl, preferably, said process comprising the step of reacting a compound according to Formula (II) [R—C(═O)Cl] with a compound according to Formula (III) to obtain the compound according to Formula (I) and to the use of these compounds as internal donor in Ziegler-Natta catalysis of olefins.
