Abstract
The present invention refers to the synthesis of precatalysts and the use of such precatalysts in ethylene oligomerization reactions for the selective production of alpha-olefins. More specifically, it refers to the preparation and use of coordination compounds containing polydentate ligands comprising Group 6 and 10 transition metal compounds, in particular chromium (III) and nickel (II). Such catalytic precursors present high catalytic activity and selectivity for the production of alpha-olefins.
