The palladium-catalyzed Sonogashira cross-coupling reaction of terminal alkynes with aryl halides is one of the most valuable methods for the synthesis of internal arylated alkynes. This reaction is typically performed in the presence of catalytic amounts of a palladium complex and copper iodide with a base. Here we have demonstrated that Na-Y zeolite can serve as a suitable inorganic support for selective organic functionalization. In this project a new and simple route for synthesis of nano-sized Pd +2 particles into Na-Y and Na-ZSM-5 zeolites via a new carbene N-heterocyclic ligand has been developed. In the part one of the work N-Heterocyclic Carbene was used as the carbene ligand, an ionic liquid ( 1-butyl-3-methylimidazolium chloride ) was synthesized into the pores of zeolites and then C-H bond was activated by a weak base (acetate) for preparing the carbene. The synthesized carbene was coordinated with palladium ions. Different techniques such as FT-IR, XRD, UV-Vis, and TEM were used for characterization of the catalysts. TEM analysis reveals that well separated nano-sized (1-2 nm) palladium (+2) particles have been formed into the pore of the zeolites. The catalytic performance was examined in the Sonogashira reactions. The products were analyzed by GC and GC-MS. Furthermore The catalyst were effective for Sonogashira coupling. The Sonogashira reaction of some aryl iodides with phenyl acetylene was studied within 24 h at 80 °C in an environmental-friendly reaction system with DMF/H 2 O as solvents and without any copper and amine. The fate of reactants and the probability of forming products are determined by molecular dimensions and configurations. Therefore, only molecules whose dimensions are less than a critical size can enter into the pores and would have access to the catalytic sites for reaction. In the presence of [Pd(NHC)]-ZSM-5 the reaction of p-nitro iodobenzene, m-iodotoluene and m-bromo iodobenzene did not occur to an acceptable extent and it should be mentioned that the reaction did not occur on some other aryl halides such as m-nitro iodobenzene and m-iodoanisole. However, in the presence of [Pd(NHC)]-Y these substrates produced product with good yield. The catalysts can be recovered and recycled by a simple decantation. the reaction conditions were optimized for the reaction,The effect of various factors such as temperature, time and amount of catalysts were also optimized.
