Ionic liquid promoted palladium-catalyzed Suzuki cross-couplings of N-contained heterocyclic chlorides with naphthaleneboronic acids

Readily available N-contained heterocyclic chlorides were coupled with naphthaleneboronic acids in ionic liquids. Desired products with good purity and high yield were obtained with short reaction time and easy isolation. Based on these advantages, we expect the efficient synthesis of these compounds can play an important role in OLEDs.
