We present herein our results on the synthesis of 3-alkynyl-dihydroselenophenes by palladium-catalyzed Sonogashira cross-coupling of 3-iododihydroselenophenes with different alkynes under mild conditions in good to excellent yields. The developed protocol tolerated a wide range of functional groups in the dihydroselenophenes and alkynes. These 3-alkynyldihydroselenophenes, bearing the chalcogen group
