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