Abstract

[GRAPHICS]Disubstituted alkynes reacted with alkenyl iodide in the presence of a catalytic amount of Pd(OAC)(2) and Ag2CO3 to give pentasubstituted fulvene derivatives in excellent yields. Other Ag salts such as AgNO3, AgBF4, and AgOTf are not effective, whereas a combination of AgNO3 and K2CO3 has a remarkable effect on the formation of fulvene.
