2-Substituted Phenanthroline Ligand

Faster Cu-catalyzed trifluoromethylation

Introducing an oxygen coordination site at the 2-position of 1,10-phenanthroline significantly shortens the reaction time for Cu-catalyzed trifluoromethylation of aryl iodides and extends the scope to various aryl bromides.
