Herein, we reported the synthesis of a new series of Pd-based complexes bearing N-heterocyclic carbene (NHC) and triphenylphosphine (PPh3) ligands. These complexes have been prepared from the (NHC)Pd(II)(pyridine) complexes and PPh3. All (NHC)Pd(II)PPh3 complexes have been characterized by using 1H NMR, 13C {1H}NMR, 31P {1H}NMR, and FTIR spectroscopy and elemental analysis technique. Here, as a result of low catalyst [(NHC)Pd(II)PPh3] loading (0.01 mmol), acetylene derivatives with various functional groups were synthesized from the coupling of phenylacetylene with various aryl bromides in the aqueous medium.
