A new entry in direct arylation of heteroarenes using Pd(OAc)2 and 1,10-phenanthroline as a nitrogen-based ligand is reported. The long induction period observed at the initial stage of the reaction was effectively reduced by modification of the catalyst preparation, leading to improved chemical yields (69-92%) and shortening of reaction times (3-10 h).
