Versuchsvorschrift

A solution of 3-iodophenyl acetate (5.6 g) (J. Org. Chem. 1983, 48,1542-4) in acetonitrile (100 mL) was treated with (Ph3P)2PdCl2 (673 mg) and Cul (368 mg) and stirred at room temperature. 3-Butyn-1-ol (1.78 g) was added and the reaction mixture stirred for a further 20 h and concentrated in vacuo. The residue was purified by chromatography (SPE, gradient from cyclohexane to DCM) to give the title compound. LCMS RT=2.54 min
