Abstract

The application belongs to the field of catalytic chemistry, and particularly relates to a 1,10-phenanthroline ligand derivative, and preparation and application thereof. The application provides a derivative of a 1,10-phenanthroline ligand as shown in formula (I) with an amide group introduced at positions 2 and 9. The 1,10-phenanthroline ligand derivative with an amide group introduced at positions 2 and 9 can enhance metal coordination ability, optimize chelation stability with metals, and can be used as a high-efficiency metal catalyst ligand to catalyze organic reactions. The 1,10-phenanthroline ligand derivative can form stable metal coordination with transition metals such as iron, cobalt and nickel, and can efficiently catalyze trifluoromethylation reaction, Ullmann type etherification reaction and polymeric ester polymerization in cooperation with copper and zirconium alkoxide.
