Ethylene Oligomerization by Ni(II) Complex Based on Peptide

Abstract:

A kind of peptide based Ni (II) complexes (general formula [ZN=C(An)-C(An)=NZ](NiBr₂)₂, Z=(4-NHR-3,5-C₆H₂(CH₃)₂)₂CH(4-C₆H₅), R=dipeptide, An=acenaphthenequinone) has been synthesized. Ethylene oligomerizations were carried out by using those complexes in combination with ethyl aluminium sesquichloride (EAS) and produced olefin . The effects of important parameters such as temperature and EAS concentration. on the catalytic activity and the distribution of resulting oligomer were investigated. under the conditions of employing toluene as solvent, a reaction temperature of 50°C and an ethylene pressure of 1.0 MPa..
