Abstract
A variety of 5-vinyl-4-pentynoic acids (12 examples) have been prepared in good to high yield by reacting vinyl triflates (1-cycloalkenyl trifluoromethanesulfonates) and 4-pentynoic acid at room temperature in dimethyl sulfoxide in the presence of diethylamine or diisopropylamine and catalytic amounts of diacetatobis(triphenylphosphine)palladium [Pd(OAc)2(PPh3)2] and copper(I) iodide.Keywords
