Abstract

Ni complex was prepared from bipyridine dicarboxylic acid and Ni salt. Then, the Ni complex was reacted with Al salt in dimethyl formamide in an autoclave to prepare metal-organic framework (MOF) compounds containing Ni-complex. IR analysis indicated disappearance of absorption peaks related to carboxylic acid, and nitrogen-adsorption isotherm analysis revealed the presence of micropores. MOF compounds containing Ni complex were used as catalysts for oligomerization of ethylene. Diethyl aluminum chloride or MOF containing Ni complex was inactive for the reaction. However, MOF compounds containing Ni complex used with diethyl aluminum chloride had high potential as a catalyst for the oligomerization of ethylene with high selectivity for linear butenes.
