| Abstract | The invention relates to a process for preparing (2,3) disubstituted succinates that allows (2,3) disubstituted succinates to be obtained in good purity and with acceptabel reaction yields. The (2) and (3) substitutions may be the same or different. The process comprises reacting a haloacetate with a malonic acid ester into a tricarboxylate, which is further reacted to a (2,3) disubstituted tricarboxylate, hydrolysed, decarboxylated and optionally esterified. Esterified (2,3) disubstituted succinic esters may be used as internal donor in Ziegler-Natta type catalysts for the polymerisation of olefins. |
