摘要
A practical and efficient liquid-phase synthesis of 1,2,3-triazoles using poly（ethylene glycol） as support in aqueous solution was described. The title compounds, 1,2,3-triazoles 5 were obtained by a one-pot three-component 1,3-dipolar cycloaddition reaction in middle yields. In addition, a series of unexpected products 7 of Sonogashira reaction were also formed under the same condition.
