The synthesis of new functionalized vinyl ethers (VE) by transetherification reaction between ethyl vinyl ether (EVE) and different alcohols is presented in this study. An air-stable palladium catalyst generated in situ efficiently catalyzed the reaction leading to various VE in a single step with good conversion % (50-82%) and good yields (up to 75%). The reaction conditions were optimized in terms of the initial EVE/alcohol molar ratio, alcohol concentration, solvent, presence and nature of the ligand, amount of the catalyst, and choice of the metal precursor. All VE were characterized using 1 H and 13 C NMR spectroscopy.
