Microwave-assisted synthesis of novel perimidinium salts as N-heterocyclic carbene precursors: involvement in palladium-catalyzed cross-coupling reactions

摘要

In the current study five novel perimidinium chlorides were synthesized in good yields by reaction of 1-(3-methylbenzyl)perimidine with five different alkyl chlorides under microwave irradiation in 30 minutes. Synthesized compounds were characterized by IR, ~1H, ~(13)C NMR spectroscopic methods and elemental analyses. Performance of in situ formed catalytic system which consist of the perimidinium salts and Pd(OAc)_2 was investigated for Heck and Suzuki reactions in aqueous media and desired products were obtained in good yields.
