| Abstract: | A convenient, easily separated method was developed for the preparation of 1-methyl-3-mPEGimidazolium iodide （L） by tosylation of polyethylene glycol monomethyl ether mPEG750, iodination of mPEG tosylate and then reacted with 1-methylimidazole. The catalytic activity was studied with palladium catalyzed Suzuki coupling reaction between aryl boronie acid and 2,7-dibromo fluorene derivatives, NMR spectroscopy indicated the products were pure enough. |
