| Abstract: | Diacetoxyiodo benzene(DIB) is an important and practically useful commercial available compound. In order to explore DIB useful scope as an environmentally more benign oxidizing reagent,a novel and efficient synthesis of diynes was studied in the absence of palladium catalysts. It was found that terminal alkynes were reacted with DIB,CuCl and Et3N in CH3CN at room temperature,diynes were prepared in good yields in a short time,which providing a simple method for the synthesis of diynes. |
