Free-radicaladdition (AIBN, 65–70 °C, 5–7 h) of secondary phosphine selenides to arylacetylenes proceeds stereoselectively to give anti-Markovnikov adducts of predominantly Z-configuration (up to 97%) in 60–80% isolated yields, thus representing a rare example of stereoselective free-radicaladdition to the triple bond. Microwave irradiation (600 W) of the reactants with the same content of AIBN reduces
