Abstract
3-(2-Iodophenyl)-3-oxopropanoic acid derivatives reacted efficiently with various terminal alkynes in the presence of catalytic amounts of dichlorobis(triphenylphosphine)palladium and copper(I) iodide and two molar amounts of triethylamine in N, N-dimethylformamide at room temperature to afford the corresponding ( Z)-2-[( Z)-3-alkylideneisobenzofuran-1(3 H)-ylidene]acetic acid derivatives in reasonable yields.
