| Abstract: | Polyethylene glycol-supported N-heterocyclic carbene palladium complex 1-PEG(10000)] have been prepared from PdCl{(η5-C5H5)]Fe(η5-C5H3)-NC5H3-Br]}(C3N2H2)(C6H3-2C3H7)2] 1 and PEG-10000.The compound has been characterized by infrared spectroscopy and 1H NMR.Using 1-PEG(10000) as catalyst in the presence of K3PO4 as base in water at 100oC provided coupling products in excellent yields.Moreover,the above system could be recycled and reused three times. |
