Breaking the Base Barrier: An Electron-Deficient Palladium Catalyst Enables the Use of a Common Soluble Base in C–N Coupling

Journal of the American Chemical Society, 2018
Due to the low intrinsic acidity of amines, palladium-catalyzed C–N cross-coupling has been plagued continuously by the necessity to employ strong, inorganic, insoluble bases.
