Özet
Four bis(3,4,5,6-tetrahydropyrimidinium) chlorides (2a-d) have been prepared and characterized by conventional spectroscopic methods and elemental analyses.A highly effective, easy to handle and environmentally benign process for palladium mediated Suzuki cross-coupling was developed.The in situ prepared three-component system Pd(OAc) 2 / bis(3,4,5,6tetrahydropyrimidinium) chlorides (2a-d) and K 2 CO 3 catalyses quantitatively the Suzuki crosscoupling of deactivated aryl chlorides.
