Homogeneous catalytic dimerization of propylene with bis(imino)pyridine vanadium(III) complexes

A series of new bis(imino)pyridine vanadium(III) complexes was synthesized. They were tested for the homogeneous catalytic dimerization of propylene after activation with MAO. The activity and selectivity depend on the ligand structure of the corresponding organic coordination compound. The influence of PPh3 as an additive was investigated and high dependency could be observed.

Based on new own and known published bis(imino)pyridine vanadium(III) complexes the catalytic dimerization of propylene was performed under homogeneous conditions. The additive PPh3 was an important point for the product selectivity.Figure optionsDownload high-quality image (48 K)Download as PowerPoint slide
