In situ generated palladium catalysts bearing 1,3-dialkylperimidin-2-yline ligands for Suzuki reactions of aryl chlorides
Four new 1,3-dialkylperimidinium halides have been prepared and characterized. The in situ prepared three component system Pd(OAc)(2)/1,3-dialkylperimidinium (1a-d) and Cs2CO3 catalyses the Suzuki cross-coupling of deactivated aryl chloride substrates in excellent yields under mild conditions.
